A general rational solution of an equation associated with perfect cuboids

Abstract

We show by finding an explicit parametrization that a 4th degree surface which arises as a necessary condition for the existence of a perfect cuboid is a rational surface, i.e. birationally equivalent over $\mathbb{Q}$ to a plane.
