Presentation

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

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

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

Polycyclic presentation:
