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