Presentation

minimal degreeμ(G) = 40
transitive degreeμt(G) = 64

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

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