Re: Determinant 1

Sorry about revising the revision on the Modular Group page; i hit submit without adding a comment; the reason unit determinant differs from determinant 1 is that in a ring (such as the ring of all 2x2 matrices, or in this case Z), a unit is anything invertible. In particular, the original reading could lead to an interpretation that the determinant was 1 or -1, which if you remove the identification criterion, reads as a quotient of GL2Z rather than SL2Z. The example I gave had determinant 1, but I meant it to have determinant -1, whoops!

Sorry if this isn't the place to chat with a user, I'm not super well-versed with this :)

Warning Templates

Hello. Regarding the recent revert you made to Fibonacci number: you may already know about them, but you might find Wikipedia:Template messages/User talk namespace useful. After a revert, these can be placed on the user's talk page to let them know you considered their edit inappropriate, and also direct new users towards the sandbox. They can also be used to give a stern warning to a vandal when they've been previously warned. Thank you.
