Presentation

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

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

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

Polycyclic presentation:
