Presentation

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

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

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