Presentation

minimal degreeμ(G) = 40
transitive degreeμt(G) = 128

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

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