Presentation

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

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

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