%N Numbers n such that 1+prime(n) and 1+prime(n+1) are the product of the same number of primes.
%C Number of primes counted with multiplicity. - _Harvey P. Dale_, Sep 05 2021
%e 2 is in the list since 1 + prime(2) = 4 and 1 + prime(3) = 6 are both products of 2 primes.
%e 4 is in the list since 1 + prime(4) = 8 and 1 + prime(5) = 12 are both products of 3 primes.
