Presentation

minimal degreeμ(G) = 39
transitive degreeμt(G) = 1216

A minimal faithful permutation representation — 4 generators on 39 points:

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