Presentation

minimal degreeμ(G) = 23
transitive degreeμt(G) = 224

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

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