	EXAMPLE	`a(64) = 5, as 64 = 2^6 = 2^(2^13^1) and there are 5 nodes in that superfactorization. Similarly, for 360 = 2^(3^1) 3^(2^1) * 5^1 we get a(360) = 8. See comments at A106490.`
	CROSSREFS	`a(n) = A106494(A106444(n)). a(n) = A106490(n)+A064372(n). Cf. also A106492.` `Sequence in context: A141829 A111336 A083902 this_sequence A073184 A073182 A049599` `Adjacent sequences: A106488 A106489 A106490 this_sequence A106492 A106493 A106494`
