Unitriangular matrix group:UT(4,3)

Definition
This group is defined in the following equivalent ways:


 * It is the unitriangular matrix group of degree four over the field of three elements.
 * It is a $$3$$-Sylow subgroup of general linear group:GL(4,3), and hence also of special linear group:SL(4,3), projective general linear group:PGL(4,3), and projective special linear group:PSL(4,3).
