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