Presentation

minimal degree	μ(G) = 40
transitive degree	μ_t(G) = 64

A minimal faithful permutation representation — 2 generators on 40 points:

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