Presentation

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

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

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

Polycyclic presentation:
