- The n-th highly composite number equals the a(n)-th composite number, for n >= 3.at n=29A074329
- Primes of the form 8n^2 + 5.at n=28A201612
- Primes less than 1000000 sorted lexicographically in decimal representation.at n=28A210761
- Let u defined by u(1) = p and for 1 < i, u(i) = u(i-1) + primorial(i), such that all u(i) are primes for 1 <= i <= k, and u(k+1) is not prime. Let m the length of the longest run of primes obtained when u is repeatedly applied to an n-digit p. Triangle read by rows: for 1 <= n, 1 <= k <= m, T(n,k) is the least n-digit prime p beginning a run of only k primes when applied u, or -1 if no such prime p exists.at n=43A356732
