This site is supported by donations to The OEIS Foundation.

 Please make a donation to keep the OEIS running. We are now in our 55th year. In the past year we added 12000 new sequences and reached 8000 citations (which often say "discovered thanks to the OEIS"). We need to raise money to hire someone to manage submissions, which would reduce the load on our editors and speed up editing. Other ways to donate

# Source file for Index to OEIS

The alphabetical sections of the Index are created "on the fly" from the following plain text file.
This file is useful if you want to search the whole Index, or suggest additions or changes.

The actual file contains less than and greater than signs and quotation marks. To make them visible, these have been replaced here by their html equivalents.

partitions, | notes on (01): When considering partitions of n (initially labeled) objects, we may:
partitions, | notes on (02): (1)  Allow the "blocks" to be empty - so more generally refer to "pieces".
partitions, | notes on (03): (2)  Order the pieces - so consider "sequences" of pieces instead of "collections".
partitions, | notes on (04): (3)  Order the elements within the pieces - so consider "lists" instead of "sets".
partitions, | notes on (05): (4)  Erase the labels on the objects - this produces partitions or compositions of integers.
partitions, | notes on (06): With these considerations in mind, we define 6 rows of a table.  The columns are defined by formulating various conditions on how many objects can be in the pieces.  The six rows are:
partitions, | notes on (07): Row A:  Sequences of lists of labeled elements (e.g. books on shelves)
partitions, | notes on (08): Row B:  Sequences of sets of labeled elements (i.e. ordered partitions)
partitions, | notes on (08): Row C:  Sequences of multisets on one color of marble (i.e. compositions)
partitions, | notes on (09): Row D:  Collections of lists of labeled elements (e.g. stacks of books)
partitions, | notes on (10): Row E:  Collections of sets of labeled elements (i.e. set partitions)
partitions, | notes on (11): Row F:  Collections of multisets on one color of marble (i.e. integer partitions)
partitions, | notes on (12): In the columns, m is the number of marbles and b is the number of bins.
partitions, | notes on (13): Column 1:  m  elements.  Each block has at least 1 element (and number of blocks varies)
partitions, | notes on (14): Column 2:  m  elements.  Each block has at least 2 elements (and number of blocks varies)
partitions, | notes on (15): Column 3:  m  elements.  Each block has 1 or 2 elements (and number of blocks varies)
partitions, | notes on (16): Column 4:  b blocks.  Each block has exactly 2 elements (and there are 2b elements)
partitions, | notes on (17): Column 5:  b pieces.  Each piece has 0 or 1 elements (and number of elements varies)
partitions, | notes on (18): Column 6:  b pieces.  Each piece has 0, 1, or 2 elements (and number of elements varies)
partitions, | notes on (19): Column 7:  b blocks.  Each block has 1 or 2 elements (and number of elements varies)

primes, in arithmetic progressions: (01) Consider n-term arithmetic progressions (APs) of primes, i, i+d, i+2d, ..., i+(n-1)d. We can minimize (a) the first term i, (b) the common difference d, or (c) the last term, l=i+(n-1)d.  This gives rise to 12 sequences since for each problem we can list the values of i, d, l, and we can list the progressions as the rows of a triangle:
primes, in arithmetic progressions: (02) problem (a) i: A007918* (assuming k-tuple cojecture), d: A061558, l: A120302, triangle: A130791
primes, in arithmetic progressions: (03) problem (b) i: A033189, d: A033188*, l: A113872, triangle: A133276
primes, in arithmetic progressions: (04) problem (c) i: A113827, d: A093364, l: A005115*, triangle: A133277
primes, in arithmetic progressions: (05) If we take the initial value to be the n-th prime (A000040) the the sequences are: d: A088430, l: A113834, triangle: A133278
primes, in arithmetic progressions: (06) One may also ask for n consecutive primes in arithmetic progression: this gives A006560.
primes, in arithmetic progressions: (07) One may also consider n consecutive numbers in arithmetic progression having the same prime signature, and ask the same questions. This gives the following sequences:
primes, in arithmetic progressions: (08) problem (a) i: A133279, d: A113461, l: A127781, triangle: A113460
primes, in arithmetic progressions: (09) problem (b) i: A034173, d: the all-ones sequence A000012, l: A034174, triangle: A083785
primes, in arithmetic progressions: (10) problem (c) i: A087308, d: A087310, l: A133280, triangle: A086786
primes, in arithmetic progressions: (11) One may also ask for n consecutive numbers with the same prime signature: this gives sequences A034173, A034174, A083785 again. See also A087307.

T-coordinates for arrays: (01) <a NAME="Tcoords">sequences related to (start):</a>
T-coordinates for arrays: (02) The usual coordinates for a triangular array are are T(n,k), with n >= 0 and 0 <= k <= n, as follows:
T-coordinates for arrays: (03) .............T(0,0)
T-coordinates for arrays: (04) .........T(1,0) T(1,1)
T-coordinates for arrays: (05) ......T(2,0) T(2,1) T(2,2)
T-coordinates for arrays: (06) ...T(3,0) T(3,1) T(3,2) T(3,3)
T-coordinates for arrays: (07) ................................
T-coordinates for arrays: (08) with associated generating function T(x,y) = Sum_{n >= 0, 0 <= k <= n} T(n,k) x^n y^k.
T-coordinates for arrays: (09) Sometimes it is more convenient to relabel the entries using U-coordinates U(i,j), i >= 0, j >= 0, i+j = n, as follows:
T-coordinates for arrays: (10) .............U(0,0)
T-coordinates for arrays: (11) .........U(1,0) U(0,1)
T-coordinates for arrays: (12) ......U(2,0) U(1,1) U(0,2)
T-coordinates for arrays: (13) ...U(3,0) U(2,1) U(1,2) U(0,3)
T-coordinates for arrays: (14) ................................
T-coordinates for arrays: (15) with associated generating function U(z,w) = Sum_{i >= 0, j >= 0} U(i,j) z^i w^j.
T-coordinates for arrays: (16) Of course U(x,y) = T(x, y/x), T(x,y) = U(x,xy).
T-coordinates for arrays: (17) E.g. for Pascal's triangle A007318 with T(n,k) = binomial(n,k) we have T(x,y) = 1/(1-x*(1+y)), U(z,w) = 1/(1-z-w), the latter being rather nicer.

two-way infinite sequences (01): Many sequences can be extended backwards in a natural way. For example, the Fibonacci numbers (A000045) extend backards to give the two-way infinite sequence
two-way infinite sequences (02): ..., -21, 13, -8, 5, -3, 2, -1, 1, 0, 1, 1, 2, 3, 5, 8, 13, 21, ..., satisfying F(n) = F(n-1) + F(n-2) = -(-1)^n F(-n) for all n.  The backwards portion here is the same sequence but with signs, which is quite common, but in general a different sequence is obtained.
two-way infinite sequences (03): The following is a list of two-way infinite sequences. A pair in parentheses indicates that the backwards and forwards sequences are different. This entry is based on communications from Michael Somos.
