Presentation

minimal degree	μ(G) = 23
transitive degree	μ_t(G) = 96

A minimal faithful permutation representation — 4 generators on 23 points:

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

Polycyclic presentation:
