Presentation

minimal degreeμ(G) = 33
transitive degreeμt(G) = 640

A minimal faithful permutation representation — 4 generators on 33 points:

(1,2,3,4,5)(6,7)(8,9)(10,11)(12,16)(13,14)(15,17)(18,19)(20,22)(21,28)(23,26)(24,27)(25,30)(29,33)(31,32);(11,14)(15,16)(18,20,24,26)(19,22,27,23)(21,25,31,33)(28,30,32,29);(7,9)(18,21,24,31)(19,25,27,33)(20,28,26,32)(22,29,23,30);(10,12,13,17)(11,15,14,16)(18,22,24,23)(19,20,27,26)(21,29,31,30)(25,28,33,32)
