Presentation

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

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

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