Presentation

minimal degreeμ(G) = 36
transitive degreeμt(G) = 64

A minimal faithful permutation representation — 4 generators on 36 points:

(2,4)(11,15)(22,27)(23,28)(34,35);(1,2,3,4)(5,6)(7,15,17,11)(8,13)(9,14)(10,12)(16,27,29,22)(18,28,31,23)(19,24)(20,26)(21,25)(30,35,32,34)(33,36);(5,7,8,18,9,16,20,30,10,17,19,31,21,29,33,32)(6,11,13,23,14,22,26,34,12,15,24,28,25,27,36,35);(7,16,17,29)(8,19)(11,22,15,27)(13,24)(18,32,31,30)(20,33)(23,35,28,34)(26,36)
