Presentation

minimal degreeμ(G) = 23
transitive degreeμt(G) = 112

A minimal faithful permutation representation — 4 generators on 23 points:

(1,2,4,6,7,5,3)(9,15)(13,21)(14,23)(20,22);(8,11,12,19)(9,14,15,23)(10,16,17,18)(13,20,21,22);(8,10,12,17)(9,13,15,21)(11,18,19,16)(14,22,23,20);(2,3)(4,5)(6,7)(8,9)(10,13)(11,14)(12,15)(16,20)(17,21)(18,22)(19,23)
