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