摘要
Given a group G of order p(1) p(2), where p(1), p(2) are primes, and F(q), a finite field of order q coprime to p(1) p(2), the object of this paper is to compute a complete set of primitive central idempotents of the semisimple group algebra IF(q)[G]. As a consequence, we obtain the structure of F(q) [G] and its group of automorphisms.
