OEIS Sequences

Values of n such that L(10) and N(10) are both prime, where L(k) = (n²+n+1)*2^2·k + (2·n+1)*2^k + 1, N(k) = (n²+n+1)*2^k + n. A227448

Numbers k that divide the sum of digits of 13^k. A175525

Triangle read by rows: T(n,k) is the number of unlabeled nonseparable (or 2-connected) loopless multigraphs with n edges on k nodes and degree >= 3 at each node, n >= 3, 2 <= k <= floor(2·n/3). A46752

Number of inequivalent leaf-colorings of planted achiral trees with n nodes. A318228

Triangle, read by rows, defined by T(n,k) = T(n-1,k) + T(n,k-1) for nk>0, where T(n,0) = T(n-1,0) + T(n-1,n-1) and T(n,n) = T(n,n-1) for n>0 with T(0,0)=1. A129577

Triangle, read by rows, T(n,k,q) = c(k,q) + c(n-k,q) - c(n, q) where c(n,q) = ∏_j=1..n-1 ((q^j+1 - 1)/(q-1)) and q = 4. A172093

a(n) = ∑_k=1..n² d(k), d(k) = number of divisors of k (A000005). A175346

Numbers n for which |n/ζ(2) - Q(n)| sets a new record, where Q(x) is the number of squarefree numbers up to x. A275390
