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