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