Presentation

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

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

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

Polycyclic presentation:
