EXAMPLE

a(1)=16467033 because it is the product of 5 distinct primes (3,11,17,149,197), and so is a(1)+1: 16467034 (2,19,23,83,227), and so is a(1)+2: 16467035 (5,13,37,41,167).


PROG

(PARI) forstep(n=1+10^7, 1e8, 4, for(k=n, n+2, issquarefree(k)next(2)); for(k=n, n+2, omega(k)==5next(2)); print1((n)", ")) \\ M. F. Hasler, May 19 2014
