Presentation

minimal degree	μ(G) = 40
transitive degree	μ_t(G) = 512

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

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