Presentation

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

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

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