Presentation

minimal degreeμ(G) = 34
transitive degreeμt(G) = 324

A minimal faithful permutation representation — 3 generators on 34 points:

(2,3)(5,8)(6,12)(7,15)(9,10)(11,21)(13,14)(16,23)(17,22)(18,28)(19,27)(20,26)(24,25)(29,30)(31,32,33,34);(1,2,3);(4,23,17,24,28,26,6,5,27,7,30,21,13,10,9,14,11,29,15,19,8,12,20,18,25,22,16)
