Presentation

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

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

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