Presentation

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

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

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

Polycyclic presentation:

GAP

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