• Number of f-vectors for simplicial complexes of dimension at most 4 on at most n-1 vertices.at n=8A011829
• f-vectors for 2-neighborly simplicial complexes on n+1 vertices.at n=6A011834
• Even square pyramidal numbers.at n=25A015222
• Concatenation of prime factors of n is a cube.at n=10A038841
• Numbers n such that 9^n + 8 is prime.at n=15A217385
• Number of blocks in a Steiner Quadruple System of order A047235(n+1).at n=34A228124
• a(n) = n*(2*n + 1)*(4*n + 1)/3.at n=26A258582
• a(n) = A273059(4n+2).at n=38A275918
• Numbers k such that N = k^6 is a twin rank (cf. A002822: 6N +- 1 are twin primes).at n=19A326236
• 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 vertices in the resulting planar graph.at n=40A367183
