Let K be a finite field of characteristic p > 2, and let M 2 Γ°KΓ be the matrix algebra of order two over K. We describe up to a graded isomorphism the 2-gradings of M 2 Γ°KΓ. It turns out that there are only two nonisomorphic nontrivial such gradings. Furthermore, we exhibit finite bases of the grade

In this paper we prove that the polynomial identities of the matrix algebra of order 2 over an infinite field of characteristic p / 2 admit a finite basis. We exhibit a finite basis consisting of four identities, and in ''almost'' all cases for p we describe a minimal basis consisting of two identit
