Definition of simili-primes of order k: Start with the natural numbers 2,3,4,5,... Define an atom to be the k-th integer which cannot be divided by another atom. The first atom is k+1. Repeat. Order 1 gives the primes A000040, order 2 gives A123929. Orders 4,5,... give A126619, A126620, A126621, ...
Invented by Hugo van der Sanden and Eric Angelini, computed by Mensanator.
