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