Presentation

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

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

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

Polycyclic presentation:
