minimal degreeμ(G) = 40
transitive degreeμt(G) = 128

A minimal faithful permutation representation — 3 generators on 40 points:

(9,10,12,16,24,31,38,40,14,17,26,32,13,18,25,33)(11,19,21,34,27,39,37,28,20,35,36,29,22,30,23,15);(1,2)(3,5)(4,7)(6,8)(15,28)(19,35)(29,34)(30,39);(2,5)(3,8)(6,7)(9,11,13,27,14,20,24,22)(10,15,18,34,17,28,31,29)(12,23,25,21,26,37,38,36)(16,30,33,19,32,39,40,35)
