OEIS Sequences

Number of compositions [p(1), p(2), ..., p(k)] of n such that p(j) ≠ p(j-2). A224958

a(n) = n*(n + 11)*(n + 22)*(n + 33)/24. A264448

Smallest b such that the k consecutive primes starting with prime(n) are all base-b Wieferich primes, i.e., satisfy b^p-1 == 1 (mod p²). Square array A(n, k), read by antidiagonals downwards. A286816

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..3, with k running over the positive integers; square array, read by antidiagonals, downwards. A319061

a(n) is the smallest b > 1 such that prime(n), prime(n+1), prime(n+2) and prime(n+3) are all base-b Wieferich primes. A344828

Lexicographically earliest sequence of nonnegative integers such that two distinct terms differ by at least 4 decimal digits. A346000
