## 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.
