• Partial sums of cuban primes A002407, that is, primes equal to the difference of two consecutive cubes.at n=23A221793
• Number of (undirected) Hamiltonian paths in the n-triangular honeycomb queen graph.at n=3A289704
• Place two n-gons with radii 1 and 2 concentrically, forming an annular area between them. Connect all the vertices with line segments that lie entirely within that area. Then a(n) is the number of regions in that figure.at n=33A337700
• Consider all 3 X 3 matrices M whose entries are the n-th to (n+8)-th primes prime(n), ..., prime(n+8), in any order. a(n) is the sum of the number of M such that det(M) is divisible by prime(n+i), for i from 0 to 8.at n=14A339105
