Presentation

minimal degree	μ(G) = 24
transitive degree	μ_t(G) = 256

A minimal faithful permutation representation — 6 generators on 24 points:

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

GAP

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