Presentation

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

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)(22,23)(24,25,29,31,28,33,27,32)(26,30,36,39,34,38,35,37);(21,23)(24,26,27,35,28,34,29,36)(25,30,32,37,33,38,31,39);(25,31)(26,34)(27,29)(30,37)(32,33)(38,39);(21,23)
