I give a 13x13 counterexample showing that 2531 does not imply 1075, and this magma ends up resolving over 1% of the remaining unknowns.
Updates the README to point out the fact that we now have a 13x13 example.

Fascinating! Was the 13x13 example constructed by hand, or created by Z3, or some mix of both? |

I give a 13x13 counterexample showing that neither of the dual pair 1076/2531 imply 1075. The constructed magma ends up resolving over 1% of the remaining unknowns.
This dual pair had by far the highest unknown count, and is among those equations that are not implied by anything else (except for x=y).
