Presentation

minimal degreeμ(G) = 39
transitive degreeμt(G) = 224

A minimal faithful permutation representation — 4 generators on 39 points:

(1,2,3,4,5,6,7)(8,9)(10,19)(11,23,26,16)(12,17)(13,27)(14,18)(15,21)(20,34,36,33)(22,30)(24,38,25,32)(28,31)(29,35,37,39);(8,10)(9,15)(11,20)(12,21)(13,28)(14,22)(16,29)(17,30)(18,31)(19,27)(23,37)(24,35)(25,39)(26,36)(32,34)(33,38);(8,11)(9,16)(10,20)(12,24)(13,25)(14,26)(15,29)(17,32)(18,23)(19,33)(21,35)(22,36)(27,38)(28,39)(30,34)(31,37);(8,12,14,13)(9,17,18,27)(10,21,22,28)(11,24,26,25)(15,30,31,19)(16,32,23,38)(20,35,36,39)(29,34,37,33)
