This is an enumeration of all finitely-presented monoids with two generators, two relations, and sum-of-sides ≤ 11:
⟨a, b | u1=v1, u2=v2⟩, where |u1| + |v1| + |u2| + |v2| ≤ 11
This enumeration has 28551 instances in total, after filtering out instances that are trivially isomorphic or anti-isomorphic to those that appeared previously, by some combination of permuting generators, permuting relations, and reversing relations.

This means no finite complete rewriting system could be found after the maximum number of attempts.
The cardinality shown is a conservative guess based on decidable properties of the presentation.
