- First column of A083798.at n=13A083800
- Primes p such that tau(p-1)+tau(p+1) is larger than for any previous term. (Smallest prime sandwiched between more composite numbers.)at n=35A090481
- Primes of the form p + (p^2 - 1)/8, where p is also prime.at n=36A165352
- Numbers k for which d(k-1) + d(k+1) is a record, where d(k) is the number of divisors of k.at n=44A189828
- a(n) = (a(n-1)*a(n-4) + a(n-5)*a(n-8)) / a(n-9), a(0) = ... = a(8) = 1.at n=18A190783
- a(n) is the least prime p such that there are exactly n pairs of primes (q,r) with p > q > r such that q | r + p and r | q + p.at n=16A344776
