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