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