Presentation

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

A minimal faithful permutation representation — 8 generators on 24 points:

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

GAP

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

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