Presentation

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

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

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

GAP

Past the SmallGroups library coverage — no SmallGroups id. Construct it from its polycyclic presentation:
