Presentation

minimal degreeμ(G) = 21
transitive degreeμt(G) = 108

A minimal faithful permutation representation — 3 generators on 21 points:

(1,2,3)(5,7)(6,9)(8,10)(11,12)(13,17,16,15,21,18,19,14,20);(4,5,7)(6,8,11)(9,12,10)(14,20,21,16,17,18)(15,19);(5,8,12)(7,10,11)(14,17,21)(16,20,18)

Past the SmallGroups library coverage — no SmallGroups id. Construct it from a minimal faithful permutation representation:

gap> G := Group((1,2,3)(5,7)(6,9)(8,10)(11,12)(13,17,16,15,21,18,19,14,20), (4,5,7)(6,8,11)(9,12,10)(14,20,21,16,17,18)(15,19), (5,8,12)(7,10,11)(14,17,21)(16,20,18));
