Primes p such that x49 = 2 has no solution mod p, but x7 = 2 has a solution mod p. A59667
Primes that contain only the digits (2, 5, 7). A214705
Primes p for which exactly five bases b with 1 < b < p exist such that p is a base b Wieferich prime. A255208
Sum of the third largest parts in the partitions of n into 8 parts. A308996
Triangle read by rows: T(n,k) is the number of permutations of {1,2,...,n} having k up-down cycles (0<=k<=n). A cycle (b(1), b(2), ...) is said to be up-down if, when written with its smallest element in the first position, it satisfies b(1)<b(2)>b(3)<... . A186358
