Graffiti.pc and TxGraffiti are both automated conjecture-generation systems by Siemion Fajtlowicz. While Graffiti.pc focused on graph theory, TxGraffiti may encompass broader mathematical domains. Opus 5's shift to TxGraffiti suggests the caterpillar technique may find applications beyond the initial six conjectures — potentially in number theory, combinatorics, or algebra.
