Presentation

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

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

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