Presentation

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

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

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

Polycyclic presentation:
