OEIS Sequences

Nonnegative n such that 6·n² + 6·n + 1 is a square. A105038

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 vertices in that figure. A337701

Numbers k such that the sum of the proper divisors of k that have the same binary weight as k is larger than k, and no subset of these divisors sums to k. A381071

Antidiagonal sums of A147995 and A163545. A163484

Triangle t(n,k) read by rows: fibonomial ratios c(n)/(c(k)*c(n-k)) where c are partial products of a generalized Fibonacci sequence with multiplier m=3. A172339

Square array read by antidiagonals: T(n,m) (n>=1, m>=0) is the number of partitions of mn that are the sum of m not necessarily distinct partitions of n. A213086

Numbers k such that 1 and 7 occur juxtaposed in the base-8 representation of k but not of k-1. A43164
