Minimally Tantus Numbers.

Written by Michael Thomas De Vlieger, St. Louis, Missouri, 2023 1220.

Abstract.

This work explores successors to squarefree numbers k in the list of numbers n such that rad(n) = k, specifically, when k is not a prime power. We place these numbers in the context of other “tantus” numbers, i.e., those that are neither prime powers nor squarefree.
