Presentation

minimal degreeμ(G) = 34
transitive degreeμt(G) = 64

A minimal faithful permutation representation — 4 generators on 34 points:

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