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