Presentation

minimal degreeμ(G) = 24
transitive degreeμt(G) = 256

A minimal faithful permutation representation — 7 generators on 24 points:

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

GAP

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

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