OEIS Sequences

Convolution of primes with odd primes. A209403

Square array A(n,k), n >= 0, k >= 0, read by antidiagonals downwards, where A(n,k) = n! * k! * [xⁿ * y^k] 1 / ( (1-x) * (1-y) * (1 - log(1-x) * log(1-y)) ). A382823

Numbers k such that 3·R_k + 10 is prime, where R_k = 11...1 is the repunit (A002275) of length k. A256570

Numbers k such that 30·k + 11 and 30·k + 13 are twin primes. A89160

Table read by antidiagonals: Place k equally spaced points on each side of a regular n-gon and join every pair of these n·k points by a chord; T(n,k) (n >= 3, k >= 0) gives the number of regions in the resulting planar graph. A367304
