Presentation

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

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

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

Polycyclic presentation:
