OEIS Sequences

Smallest prime whose product of digits is 3ⁿ. A88653

Irregular triangle, read by rows, of primes with prefix n and digits "9" appended, otherwise 0. A185687

a(n) is the smallest m such that for any N, at least one of S(N), S(N+1), ..., S(N+m-1) is divisible by n, where S(N) is the sum of digits of N. A331788

Primes of the form 14 n²-1. A143832

Square array read by antidiagonals upwards: M(n,k) is the initial occurrence of first prime p1 of consecutive primes p1, p2, where p2 - p1 = 2·k, and p1, p2 span a multiple of 10ⁿ, n>=1, k>=1. A287050

a(n) = smallest k such that 5k has a digit sum = n. A77492

Primes of the form a^a + b^b + c^c + d^d + e^e. A136292

Primes that end in 999. A230202

a(0) = 1; thereafter a(n) = 2·a(n-1) + 1, with digits rearranged into nondecreasing order. A346296
