From the last two lemmas and the orbit-stabilizer theorem, the order is (p 2 1)(p1)p Corollary 10.5. GL 2(Z 2) is isomorphic to S 3. Proof. GL(Z 2) acts on Z 2 {0} which has 3 elements. Therefore we have a homomorphism f : G ! S 3 which is one to one because kerf consists matrices Websquares in R are the non-negative elements, x2 +1 is irreducible, so C = R[x]/(x2 +1) is a ﬁeld. Now, for any element in R[x]/(x2 +1), we can reduce higher-order terms by x2 = −1, so a generic element in C is of the form a + bx for some a,b ∈ R. If a = b = 0, then it’s clear that a+bx = 0+0x = (0+0x)2. Otherwise, let c = s a+ √ a2 +b2 ... foul words and frowns must not repel a lover
