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)(24,25,26,30)(27,36,37,33)(28,32,35,39)(29,38,31,34);(20,21,22,23)(24,25)(26,33)(27,36)(28,32)(29,35)(30,34)(31,38)(37,39)
