COMMENTS

a(n) divides A003557 but is not equal to it.

LINKS

Table of n, a(n) for n=1..104.

FORMULA

a(n)=n/(A007947(n)^A051904(n))

EXAMPLE

n=1800: the squarefree kernel is 2.3.5=30 and 900=30^2 divides n, a(1800)=2, the quotient.

CROSSREFS

A001694, A007497, A051904, A003557, A052485.

Sequence in context: A220122 A101446 A219093 * A014649 A070084 A193518
