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