OEIS Sequences

Sum of the second largest parts in the partitions of n into 7 parts. A308932

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. A367303

Numbers k such that k and k+1 have the same sum of powerful divisors (A183097) and this sum is larger than 1. A349063

a(n) = a(1) + a(2) + ... + a(n-1) - a(m) for n >= 4, where m = 2·n - 2 - 2^p+1 and p is the unique integer such that 2^p < n - 1 <= 2^p+1, starting with a(1) = 1, a(2) = 3, and a(3) = 4. A49931
