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