Presentation

minimal degree	μ(G) = 40
transitive degree	μ_t(G) = 256

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

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