Web194 Symmetric groups [13.2] The projective linear group PGL n(k) is the group GL n(k) modulo its center k, which is the collection of scalar matrices. Prove that PGL 2(F 3) is isomorphic to S 4, the group of permutations of 4 things. (Hint: Let PGL 2(F 3) act on lines in F 2 3, that is, on one-dimensional F 3-subspaces in F 2.) The group PGL Web7 Symmetry and Group Theory One of the most important and beautiful themes unifying many areas of modern mathematics is the study of symmetry. Many of us have an …

Prove that PGL 2(F 3) is … WebA conjugacy class of a group is a set of elements that are connected by an operation called conjugation. This operation is defined in the following way: in a group G G, the elements a a and b b are conjugates of each other if there is another element g\in G g ∈ G such that a=gbg^ {-1} a= gbg−1. Conjugacy classes partition the elements of a ... recommended reads for year 7
