• Numbers k such that the least term in the periodic part of the continued fraction for sqrt(k) is 24.at n=27A031702
• a(n) = 729*n^2 + 27.at n=12A158645
• Number of vertices in a regular drawing of the complete bipartite graph K_{n,n}.at n=30A331755
• Irregular table read by rows, T(n, k) is the rank of the k-th Genocchi permutation of {1,...,n}, permutations sorted in lexicographical order. If no Genocchi permutation of {1,...,n} exists, then T(n, 1) = 0 by convention.at n=33A347599
