%N A086059 Sum of first n 7-almost primes.
%C A086059 Elements in this sequence can themselves be 7-almost primes. a(1) = 128 
               = 2^7. Also a 7-Brilliant number. a(2) = 320 = 2^6 * 5. Also a 7-Brilliant 
               number. Does this happen infinitely often? - Jonathan Vos Post (jvospost3(AT)gmail.com),
