Presentation

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

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

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