Presentation

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

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

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