Finite groups with two rows which differ in only one entry in character tables. (English) Zbl 07396189

Summary: Let \(G\) be a finite group. If \(G\) has two rows which differ in only one entry in the character table, we call \(G\) an RD1-group. We investigate the character tables of RD1-groups and get some necessary and sufficient conditions about RD1-groups.
