It's a set with a binary operator, with following fulfilled: |
| 6 |
* closed with respect to the operation |
| 7 |
* the operation is associative |
| 8 |
* there is a neutral element for the operation |
| 9 |
* and there's an inverse for each element |
| 10 |
|
| 11 |
The neutral element can be shown to be unique. |
