OEIS Sequences

Number of n-step self-avoiding walks on hexagonal [ =triangular ] lattice. A1334

a(n) = self-convolution of row n of array T given by A027052. A27072

Integers n such that 6n, 36n, and 216n fall between pairs of twin primes, that is, 6n-1, 6n+1, 36n-1, 36n+1, 216n-1, and 216n+1 are prime. A192851

a(n) = [xⁿ] 1/(1 + n*(1 - theta₂(sqrt(x))/(2·x^1/8))), where theta₂() is the Jacobi θ function. A301334

Call m strict-sense Egyptian if we can partition m = x₁+x₂+...+x_k into distinct positive integers x_i such that ∑_i=1..k 1/x_i = 1; sequence gives all numbers that are not strict-sense Egyptian. A51882
