Presentation

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

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

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