Presentation

minimal degreeμ(G) = 24
transitive degreeμt(G) = 128

A minimal faithful permutation representation — 6 generators on 24 points:

(1,2);(3,4);(10,14,16,21)(11,17)(12,19)(15,20,23,22)(18,24);(5,6)(7,8);(10,15,16,23)(11,18)(14,20,21,22)(17,24);(6,8)(9,10,11,14,12,15,17,22,13,16,18,21,19,23,24,20)

GAP

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

gap> G := Group((1,2), (3,4), (10,14,16,21)(11,17)(12,19)(15,20,23,22)(18,24), (5,6)(7,8), (10,15,16,23)(11,18)(14,20,21,22)(17,24), (6,8)(9,10,11,14,12,15,17,22,13,16,18,21,19,23,24,20));
