Presentation

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

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

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

Polycyclic presentation:
