Presentation

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

A minimal faithful permutation representation — 2 generators on 39 points:

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