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