Examples of What Not to Submit

From OeisWiki

Jump to: navigation, search

The following are examples of submissions that were rejected:

  • A-numbers of sequences contributed by [your name] (however, this might be appropriate on your OEIS Wiki user page).
  • Experience points required for a Pokemon in the "erratic" experience group to be of level n.
  • The year 10^n decimal digits of pi were first computed (Not well-defined!)
  • Primes of the form n^3 + 2 n^2 + 37 n + 73.
  • Non-trivial circulation in decreasing order: numbers of the form lim_{x->+inf}(a[x]b) with b<>1.
  • You start at the number 1 and you add 2 until you get to the 4th number in the sequence, in which you then add the 1st and 3rd number of the sequence, which will give you 6. Then you do the same thing, adding 2 to each sequence, but for every 4th number you add the 1st and 3rd number before it.
  • Consecutive Quotients minus a third term x(k) = fix(a*x(k-1)/x(k-2))-b*x(k-3).
  • Prime numbers of the form 1 plus n x 10@r (@ means "to the power of") where n is an integer between 1 and 9 inclusive, and r is an integer greater than or equal to 0.
  • Concatenate a semiprime with a Fibonacci number to obtain a palindrome with at least two distinct digits.

These are only slightly exaggerated versions of earlier sequences that were rejected as inappropriate.

  • Numbers n such that d(n)+sigma(n)+phi(n)+prime(n) is a perfect cube.
  • Numbers n such that 7^n + 361*n - 5*sqrt(n) is a semiprime.
  • Successive primes encountered in decimal expansion of fifth root of 13.
  • The sequence 1,2,3 (and no further terms are known).
  • The number of bars in Beethoven's nth symphony.
  • John Doe's sequence
  • Oblong wombat numbers
  • A vector matrix Markov based on the p-adic version of the Schopenhauerian group gamma matrix.
  • Quantum eigenvalues of Buckminster Fuller's epistemological pseudomorphism.
  • Number of children of n-th Speaker of the US House of Representatives on the day he was elected.
  • Time of sunset in Woodstock, NY, on n-th day of 2016, rounded to the nearest hour.
  • Number of letters in the n-th word defined in Webster's English Dictionary.
  • Length of line when n is printed using Helvetica Regular 12-point font, rounded to nearest millimeter.
  • The number of languages spoken in the states of India in 1900+n
  • The number of policemen killed in Chicago in the year 1900+n
  • The square kilometers encompassed by the boundary of the German Reich at dawn on February 1 1900+n.
