Presentation

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

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

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

Polycyclic presentation:
