Presentation

minimal degreeμ(G) = 33
transitive degreeμt(G) = 320

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

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