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