OEIS Sequences

Let u be any string of n digits from {0,...,8}; let f(u) = number of distinct primes, not beginning with 0, formed by permuting the digits of u to a base-9 number; then a(n) = max_u f(u). A65850

Intrinsic 10-palindromes: n is an intrinsic k-palindrome if it is a k-digit palindrome in some base. A60947

Expansion of ∏_k>=1 1/(1-x^k+5)^k. A263361

Indices k such that the determinant of the 3 X 3 Hankel matrix of consecutive primes starting at prime(k) is 0. A392523

Expansion of ∏_m>=1 (1 + m·q^m)⁸. A22636
