Abstract
We describe how we machine-checked the admissibility of the standard structural rules of weakening, contraction and cut for multiset-based sequent calculi for the unimodal logics S4, S4.3 and K4De, as well as for the bimodal logic \(\mathrm {S4C}\) recently investigated by Mints. Our proofs for both S4 and S4.3 appear to be new while our proof for \(\mathrm {S4C}\) is different from that originally presented by Mints, and appears to avoid the complications he encountered. The paper is intended to be an overview of how to machine-check proof theory for readers with a good understanding of proof theory.

- 1.
Technically, there are two syntactically identical premises which individually un-box one of the two copies of \(\Box A\).
