Presentation

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

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

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

Polycyclic presentation:
