Presentation

minimal degreeμ(G) = 31
transitive degreeμt(G) = 448

A minimal faithful permutation representation — 3 generators on 31 points:

(1,2,3,4,5,6,7)(9,12,13,14)(16,17,22,25)(18,21,24,20)(19,26)(23,27)(28,30)(29,31);(8,9,10,14,11,13,15,12)(16,18,20,17,22,24,21,25)(19,26,28,23,29,31,27,30);(16,19)(17,23)(18,26)(20,28)(21,27)(22,29)(24,31)(25,30)
