Presentation

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

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

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

Polycyclic presentation:
