%N Sum of first n 8-almost primes.
%C Elements in this sequence can themselves be 8-almost primes, as happens often for 5-almost primes. a(1) = 256 = 2^8. Also an 8-Brilliant number. a(2) = 640 = 2^7 * 5. Also an 8-Brilliant number. Does this happen infinitely often? - _Jonathan Vos Post_, Dec 11 2004
%e a(2)=640 because sum of first two 8-almost primes i.e. 256+384 is 640.
