COMMENT

The convention in the OEIS is that squareful, cubeful (A046099), biquadrateful,... mean the same as "not squarefree" etc., while 2- or square-full, 3- or cube-full (A036966), 4-full (A036967) are used for Golomb's notion of powerful numbers (A001694, see references there), when each prime factor occurs to a power > 1. - M.
