[en] We restrict the types of 2 × 2-matrix rings which can occur as simple components in the
Wedderburn decomposition of the rational group algebra of a finite group. This results in a description up to commensurability of the group of units of the integral group ring ZG for all finite groups G that do not have a non-commutative Frobenius complement as a quotient. | |
