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