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

A minimal faithful permutation representation — 2 generators on 40 points:

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