PERMUTATION REPRESENTATION FOR THE GROUP SL(2.q) WHEN EXTENDED BY A CERTAIN GROUP OF ORDER TWO

If F is subfield of C, then a square matrix over F with non-negative integral trace is called a quasi-permutation matrix over F. for a finite group G, let p(G) denote the minimal degree of a faithful permutation representation of G. The purpose of this paper is to calculate p(G) for the group SL(2,q) when extended by a certain group of order two.
