• Denominators of the coefficients of a power series for the canonical half-exponential function.at n=22A091737
• Triangle, read by rows, where T(n,k) = n!/(k!*(n-3*k)!*3^k) for n>=3*k>=0.at n=33A118931
• Partition number array, called M32(-2), related to A004747(n,m) = |S2(-2;n,m)| (generalized Stirling triangle).at n=47A143172
• Numerator of n!/3^n.at n=11A212307
• The simple continued fraction expansion of F(x) := Product_{n >= 0} (1 - x^(4*n+3))/(1 - x^(4*n+1)) when x = (1/2)*(9 - sqrt(77)).at n=11A221367
• a(n) is the least integer that can be expressed as the difference of two octagonal numbers in exactly n ways.at n=17A334037
• T(n, k) = (3^(-k)*n!*2^(n - 3*k))/(k!*(n - 3*k)!), for n >= 0 and 0 <= k <= floor(n/3). Triangle read by rows.at n=29A344915
• Irregular triangle (an infinite binary tree) read by rows. The tree has root node 1 in row n = 1. For n > 1, each node with value m in row n-1 has a left child with value m / n if n divides m, and a right child with value m * n.at n=34A360298
