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