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