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