• Sum of the second largest parts in the partitions of n into 7 parts.at n=45A308932
• Numbers k such that k and k+1 have the same sum of powerful divisors (A183097) and this sum is larger than 1.at n=16A349063
• Table read by antidiagonals: Place k equally spaced points on each side of a regular n-gon and join every pair of these n*k points by a chord; T(n,k) (n >= 3, k >= 0) gives the number of internal vertices in the resulting planar graph.at n=49A367303
