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