Presentation

minimal degreeμ(G) = 36
transitive degreeμt(G) = 128

A minimal faithful permutation representation — 5 generators on 36 points:

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