| Mar 18, 2020 at 2:19 | comment | added | Frieder Ladisch | @MarkSapir This is one of several equivalent definitions of "of central type" (in this context), see the first two sentences in the cited paper. That these are equivalent is shown in Cor. 2.30 of Isaacs's book, from where the citation is. | |
| Mar 18, 2020 at 2:18 | comment | added | user6976 | It is clearer in the MathSci review of the paper. | |
| Mar 18, 2020 at 2:07 | comment | added | user6976 | It may be trivial but could you clarify why groups with the OP condition are of central type? | |
