%N A046306 Numbers that are divisible by exactly 6 primes (counted with multiplicity).
%C A046306 Also called 6-almost primes. Products of exactly 6 primes (not necessarily 
               distinct). Any 6-almost prime can be represented in several ways 
               as a product of two 3-almost primes A014612 and in several ways as 
               a product of three semiprimes A001358. - Jonathan Vos Post (jvospost3(AT)gmail.com),
