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