Abstract

Given a positive integer nn, we let sfp(n){\rm sfp}(n) denote the squarefree part of nn. We determine all positive integers nn for which max{sfp(n),sfp(n+1),sfp(n+2)}150\max \{ {\rm sfp}(n), {\rm sfp}(n+1), {\rm sfp}(n+2) \} \leq 150 by relating the problem to finding integral points on elliptic curves. We also prove that there are infinitely many nn for which max{sfp(n),sfp(n+1),sfp(n+2)}<n1/3. \max \{ {\rm sfp}(n), {\rm sfp}(n+1), {\rm sfp}(n+2) \} < n^{1/3}.

Most difficult case now done using the Heegner point method
