Presentation

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

A minimal faithful permutation representation — 5 generators on 24 points:

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

GAP

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