Presentation

minimal degreeμ(G) = 23
transitive degreeμt(G) = 192

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

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