Presentation

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

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

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

Polycyclic presentation:
