OEIS Sequences

Number of cycles that are either nonincreasing or of length 1 in all permutations of {1,2,...,n}. A cycle (b(1), b(2), ...) is said to be increasing if, when written with its smallest element in the first position, it satisfies b(1)<b(2)<b(3)<... . A186760

Expansion of 1/( ∏_k=0..8 (1 - (9·k+1) * x) )^1/9. A383632

Odd composite numbers k all of whose divisors larger than 1 are not binary palindromes (A006995) such that the divisors of the binary reversal of k (A030101) are the binary reversals of the divisors of k. A331664

Consider 3 X 3 X 3 Rubik cube, but only allow the double slice group to act; sequence gives number of positions that are exactly n moves from the start, up to equivalence under the full group of order 48 of the cube. A80623
