General linear group:GL(2,3)

Definition
The general linear group $$GL(2,3)$$ is defined in the following equivalent ways:


 * 1) It is the member of family::general linear group of degree two: $$2 \times 2$$ invertible matrices over the field of three elements.
 * 2) It is the Schur covering group of symmetric group:S4 of "+" type. The corresponding Schur multiplier (the second homology group $$H_2(S_4;\mathbb{Z})$$ is cyclic group:Z2.
