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