Abstract: We expose a new invariant for representations of the equioriented grid of dimension 2, introduced by Asashiba, Escolar, Nakashima and Yoshiwaki in 2019. It is a rich but incomplete invariant that is computable in finite time, as opposed to regular decomposition in indecomposables, which is complete but not effectively computable as the bound quiver is of wild type.
