| Jun 6, 2023 at 14:20 | comment | added | neelkanth | And I am searching except p-groups . | |
| Jun 6, 2023 at 14:19 | comment | added | neelkanth | @Mare yes same as definition of commutative ring. | |
| Jun 6, 2023 at 13:52 | comment | added | Mare | Does that mean that any two elements in the Jacobson radical commute? If yes, then a $p$-group has this property if and only if it is commutative in characteristic p since the algebra is local. This problaby also holds in general when the algebra is not semisimple. | |
