Character table sudokus

Published 24 Jan 2023 in math.RT and math.GR | (2301.09840v2)

Abstract: It is a fun game to complete a partial character table of a finite group. We show that one can reconstruct a missing row or column from a given table. The proof relies on deep properties of fully ramified characters. Moreover, we extend a classification of groups with a "large" character degree started by Snyder and continued by Durfee and Jensen.
