Presentation

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

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

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

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