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