Presentation

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

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

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