minimal degree	μ(G) = 40
transitive degree	μ_t(G) = 128

A minimal faithful permutation representation — 4 generators on 40 points:

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