• Primes of the form 16*k-1 such that 4*k-1 and 8*k-1 are also primes.at n=28A101793
• Numbers m such that Conv(b,m) = b has a unique nontrivial solution (b = 0 and b = 1 are considered trivial solutions). Here, Conv(b,m) denotes the limit of b^^t (mod m) as t goes to infinity.at n=32A347561
• Primes where every other digit is 7 starting with the rightmost digit, and no other digit is 7.at n=31A348560
• a(n) is the least prime p such that, if q is the next prime after p and d = q-p, then p-n*d, p+n*d, q-n*d and q+n*d are all prime.at n=31A353697
