Description: Alternate proof of bj-charfundc 14563. It was expected to be much shorter since it uses bj-charfun 14562 for the main part of the proof and the rest is basic computations, but these turn out to be lengthy, maybe because of the limited library of available lemmas. (Contributed by BJ, 15-Aug-2024.) (Proof modification is discouraged.) (New usage is discouraged.) |
