Basically I agree with you both. Maurice's solution is complicated, not |
| 12 |
straight-forward and probably complicated for people who don't get set theory |
| 13 |
all that well. |

However the proposed solution can also get awkward in certain cases. For |
| 16 |
example what does the negation of a group has as result when it contains a |
| 17 |
negated element. |

What I think is the best solution is to allow negation of groups only under |
| 20 |
certain conditions. One condition is that the group may not contain negations |
