Ghorbany}, country = {}, institution = {}, abstract = {A square matrix over the complex field with non- negative integral trace is called a quasi-permutation matrix. For a finite group G the minimal degree of a faithful representation of G by quasi-permutation matrices over the rationals and the complex numbers are denoted by q(G) and c(G) respectively. Finally r (G) denotes the minimal degree of a faithful rational valued complex character of C. The purpose of this paper is to calculate q(G), c(G) and r(G) for the group S L(2, q) when extended by a certain group of order two. }, journal = {International Journal of Mathematical and Computational Sciences}, volume = {1}, number = {9}, year = {2007}, pages = {463 - 465}, ee = {https://publications.waset.org/pdf/9999254}, url = {https://publications.waset.org/vol/9}, bibsource = {https://publications.waset.org/}, issn = {eISSN: 1307-6892}, publisher = {World Academy of Science, Engineering and Technology}, index = {Open Science Index 9, 2007}, }
