Presentation

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

A minimal faithful permutation representation — 4 generators on 24 points:

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

Polycyclic presentation:
