Presentation

minimal degreeμ(G) = 31
transitive degreeμt(G) = 224

A minimal faithful permutation representation — 4 generators on 31 points:

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