Presentation

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

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

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