Appears in sequences
- Consider 3 X 3 X 3 Rubik cube, but only allow the <U, R> group to act; sequence gives number of positions that are exactly n moves from the start.at n=11A080628
- a(n) is the smallest integer k such that the n-th (forward) difference of the partition sequence A000041 is positive from k onwards.at n=38A119712
- Triangle read by rows: T(n,k) is the number of partitions of the set {1,2,...,n} having k adjacent blocks (0 <= k <= n). An adjacent block is a block of the form (i, i+1, i+2, ...).at n=56A177254
- Number of binary strings of length n avoiding 4-antipowers.at n=34A275061
- Let p = n-th prime == 3 mod 8; a(n) = sum of quadratic nonresidues mod p that are < p/2.at n=33A282724
