Presentation

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

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

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