• Smallest prime in class n (sometimes written n+) according to the Erdős-Selfridge classification of primes.at n=13A005113
• Let Dedekind's psi(m) = product of (p+1)p^(e-1) for primes p, where p^e is a factor of m. Iterating psi(m) eventually results in a number of form 2^a*3^b. a(n) is the smallest number that requires n steps to reach such a number.at n=14A019268
• Primes of Erdos-Selfridge class 14+.at n=0A129474
