OEIS Sequences

Twice 12-gonal numbers: a(n) = 2·n*(5·n-4). A152965
a(n) = A002526(n+2) + A002526(n) - A002527(n+2) - A002527(n+1) + A002527(n) - A188493(n). A188492
Infinitary Zumkeller numbers (A335197) whose set of infinitary divisors can be partitioned into two disjoint sets of equal sum in a single way. A335199
Series for first parallel moment of square lattice. A6728
Numbers k such that x=(σ(k) XOR 2·k) divides k in carryless binary arithmetic, when the binary expansions of k and·are interpreted as polynomials in ring GF(2)[X]. A379236
a(n) = n*(2·n2 + 5·n + 1). A163832
