Presentation

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

A minimal faithful permutation representation — 3 generators on 36 points:

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