Appears in sequences

• Consider a 3 X 3 X 3 Rubik cube, but only allow the moves M_R, D; sequence gives number of positions that are exactly n moves from the start.at n=13A080617
• Number of (w,x,y) with all terms in {0,...,n} and |w-x| + |x-y| != w+x+y.at n=33A213480
• Number of (n+2) X (1+2) 0..1 arrays with no 3 x 3 subblock diagonal sum 0 and no antidiagonal sum 0 and no row sum 2 and no column sum 2.at n=21A255221
• Irregular triangle read by rows: T(n,i) = number of n X n semi-canonical binary matrices with exactly i 1's, where 0 <= i <= n^2.at n=84A268523
• Table read by antidiagonals: Place k points in general position on each side of a regular n-gon and join every pair of the n*(k+1) boundary points by a chord; T(n,k) (n >= 3, k >= 0) gives number of edges in the resulting planar graph.at n=32A367190
