Presentation

minimal degree	μ(G) = 23
transitive degree	μ_t(G) = 192

A minimal faithful permutation representation — 3 generators on 23 points:

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

Polycyclic presentation:
