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