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