@ArturoMagidin, Fixed.

@ArturoMagidin, I am more interested in the $A_{2n+1}$ groups, with the first one e.g. $A_{n+1}$ being a special case. See the last paragraph. Anyway, I'm going off to recalculate the parity again and will be back if I have any more questions. thanks again!

comment Prove that every element of a finite group has an order
@William Chan Yes. Supposing each denotes a vertex of a equilateral triangle on a plane, then this is a rotation.

comment Negation of if and only if?
There is no need to abreviate a truth table when the proposition has only 2 variables. Secondly, even if there was a need, the table you wrote isn't it. I recommend you remove it because it makes no sense and only serves to add confusion.
