Presentation

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

A minimal faithful permutation representation — 3 generators on 24 points:

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

Polycyclic presentation:
