OEIS Sequences

a(n) = number of 8-digit primes with digit sum n, where n runs through the non-multiples of 3 in the range [2..71]. A178879

a(1) = 1; for n > 1: a(n) = smallest odd number greater than a(n-1) which does not use any digit used by a(n-1). A229364

Smallest of three consecutive integers divisible respectively by three consecutive squares greater than 1. A178919

E.g.f. A(x) satisfies A(x) = 1/( 1 - x·cos(x·A(x)^1/2) / A(x) ). A381301

Numbers k such that numerator of Bernoulli(2·k) is divisible by 101, the fourth irregular prime. A92223

Indices of primes in sequence defined by A(0) = 93, A(n) = 10·A(n-1) - 7 for n > 0. A101002

Numbers n such that 9·10ⁿ + 2·R_n + 1 is prime, where R_n = 11...1 is the repunit (A002275) of length n. A103094
