Presentation

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

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

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