Presentation

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

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

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