Presentation

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

A minimal faithful permutation representation — 3 generators on 23 points:

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