  A relation on a $k$-net$(n)$ (or, equivalently, a set of $k-2$ mutually
orthogonal Latin squares of order $n$) is an $\mathbb{F}_{2}$ linear dependence
within the incidence matrix of the net. Dukes and Howard (2014) showed that any
6-net(10) satisfies at least two non-trivial relations, and classified the
relations that could appear in such a net. We find that, up to equivalence,
there are $18\,526\,320$ pairs of MOLS satisfying at least one non-trivial
relation. None of these pairs extend to a triple. We also rule out one other
relation on a set of $3$-MOLS from Dukes and Howard's classification.
