Presentation

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

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

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

Polycyclic presentation:
