Computational Evidence Against Quadratic-Cubic Factorization for the Second Cuboid Quintic

Valery Asiryan, Randall L. Rathbun

Let $Q_{p,q}(t)\in \mathbb{Z}[t]$ be Sharipov's even monic degree-$10$ second cuboid polynomial depending on coprime integers $p\ne q>0$. Writing $Q_{p,q}(t)$ as a quintic in $t^{2…
