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

Polycyclic presentation:
