Finding 59:29 in the Monster
The Monster, the largest sporadic finite simple group, had explicit generators available for every class of maximal subgroup except one: 59:29. We constructed its generators through a fingerprint search that examined 286 million candidates, using a custom Codex workflow to build and run the computation. The construction also yields a short new proof that the Monster has no subgroup PSL₂(59), correcting a 2004 result.
