Presentation

minimal degree	μ(G) = 24
transitive degree	μ_t(G) = 64

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

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

Polycyclic presentation:
