Hey, if you don't remember the definitions just invent your own.
Doesn't work as well in math as it does in other fields (no pun
intended) though.

I suppose he means "has a symmetric Cayley table", which is of course
not nearly enough to make it a group.

But if this represents the general level of math understanding of this
person I'd say he's got more stuff to prep on than just linear
