Deduction modulo is an extension of predicate calculus with rewriting both on terms and propositions. It is well suited for proof search in theories because it turns many axioms into rewrite rules. We also present the associated automated theorem prover Zenon Modulo, an extension of Zenon to polymorphic types and deduction modulo, along with its backend to the Dedukti universal proof checker, which also relies on types and deduction modulo, and which allows us to verify the proofs produced by Zenon Modulo. Finally, we assess our approach over the proof obligation benchmark provided by the BWare project.Keyphrases: automated deduction, b method, deduction modulo, dedukti, set theory, typed proof search, zenon modulo In: Ansgar Fehnker, Annabelle McIver, Geoff Sutcliffe and Andrei Voronkov (editors).
