Presentation

minimal degree	μ(G) = 24
transitive degree	μ_t(G) = 128

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

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

Polycyclic presentation:
