OEIS Sequences

Numbers k such that k² divides 15^k-1. A128395

Numbers k such that k³ divides 15^k² - 1. A177915

Coefficients T(n,k) of xⁿ*y^k in A(x,y) for n >= 0, k = 0..3·n+1, where A(x,y) satisfies: y = ∑_n=-oo..+oo (-x)^n² * A(x,y)^(n-1²), as an irregular triangle read by rows. A356500

Call two meanders from A005316 equivalent if they differ by a reflection in the Y axis (if n even) or by reflections in the X or Y axes (if n odd). Sequence gives number of inequivalent meanders with n crossings. A77055
