Presentation

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

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

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