Special linear group:SL(2,Z4)

Definition
The group can be defined in the following equivalent ways:


 * 1) It is the group $$SL(2,\mathbb{Z}_4)$$ or $$SL(2,\mathbb{Z}/4\mathbb{Z})$$, is defined as the defining ingredient::special linear group of degree two over the ring of integers modulo 4.
 * 2) It is the group $$SL(2,\mathbb{F}_2[t]/(t^2))$$, i.e., the special linear group of degree two over the ring $$\mathbb{F}_2[t]/(t^2)$$.
