Presentation

minimal degree	μ(G) = 24
transitive degree	μ_t(G) = 64

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

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

Polycyclic presentation:
