Presentation

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

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

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