A220658 Irregular table, where the n-th row consists of A084558(n)+1 copies of n. 5

COMMENTS

Equally, for n>=1, each i in range [n!,(n+1)!-1] occurs n+1 times.

Used for computing A220659, A055089 and A060118: The n-th term a(n) tells which permutation (counted from the start, zero-based) of A055089 or A060117/A060118 the n-th term in those sequence belongs to.

LINKS

A. Karttunen, Rows 0..720 of the irregular table, flattened.

EXAMPLE

Rows of this irregular table begin as:

0;

1, 1;

2, 2, 2;

3, 3, 3;

4, 4, 4;

5, 5, 5;

6, 6, 6, 6;

The terms A055089(3), A055089(4) and A055089(5) are 1,3,2. As a(3), a(4) and a(5) are all 2, we see that "132" is the second permutation in A055089-list, after the identity permutation "1", which has the index zero.

PROG

(Scheme with Antti Karttunen's intseq-library): (define A220658 (COMPOSE (LEAST-GTE-I 1 0 (COMPOSE A220657 1+)) 1+))
