Presentation

minimal degreeμ(G) = 39
transitive degreeμt(G) = 608

A minimal faithful permutation representation — 3 generators on 39 points:

(1,2,3,4,5,6,7,8,9,10,11,12,13,14,15,16,17,18,19)(20,21)(22,23)(24,25,28,33,29,30,27,32)(26,31,34,39,35,37,36,38);(25,30)(26,34)(27,28)(31,38)(35,36)(37,39);(21,23)(24,26)(25,31)(27,36)(28,34)(29,35)(30,37)(32,38)(33,39)
