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