Neil, SeqFans:

The first term of this sequence seems incorrect to me,
don't you agree that according to the definition (which is
perfectly well defined also for n=1), it should be a(1)=0 ?

A001055  Number of ways of factoring n with all factors >1.
	1, 1, 1, 2, 1, 2, 1, 3, 2, 2, 1, 4, 1, 2, 2, 5, 1, 4,...
	OFFSET 	1,4

However, since this is a quite old-standing sequence which also has a b-file,
I think it is worth while asking for opinions prior to any hypothetical change.

Regards,
Maximilian
