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

GAP

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