OEIS Sequences

A(n, k) is the k-th number b > 1 such that b^prime(n+i-1) == 1 (mod prime(n+i)²) for each i = 0..4, with k running over the positive integers; square array, read by antidiagonals, downwards. A319062

Numbers b > 1 such that the smallest five primes, i.e., 2, 3, 5, 7 and 11 are base-b Wieferich primes. A339534

Numbers k such that the continued fraction for sqrt(k) has odd period and if the last term of the periodic part is deleted the two central terms are both 17. A31605

Discriminants of real quadratic fields with class number 2 and related continued fraction period length of 17. A51982

Lexicographically earliest sequence of distinct positive integers such that a(n), a(n+1) and the product a(n)*a(n+1) have in common the substring n. A333933

Array T read by diagonals: T(i,j) = number of pairs (h,k) with h²+k² <= i²+j², h>=0, k >= 0. A48149
