• Square array, read by antidiagonals, where row n+1 is generated from row n by first removing terms at positions [(m+3)^2/4 - 2] for m>=0 and then taking partial sums, starting with all 1's in row 0.at n=47A135878
• Triangle, read by rows, equal to the matrix cube of triangle P = A135880.at n=28A135888
• Column 0 of triangle A135888, which equals the matrix cube of triangle A135880; also equals column 1 of triangle A135894.at n=7A135889
• Triangle R, read by rows, where column k of R equals column 0 of P^(2k+1) where P=A135880.at n=37A135894
• Triangle, read by rows equal to the matrix product R^-1*Q, where Q = A135885 and R = A135894; R^-1*Q equals triangle R shifted down one row.at n=46A135900
