Presentation

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

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

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

Polycyclic presentation:
