Presentation

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

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

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