Presentation

minimal degreeμ(G) = 20
transitive degreeμt(G) = 128

A minimal faithful permutation representation — 6 generators on 20 points:

(10,12)(13,14)(15,18)(16,17)(19,20);(1,2)(3,4)(5,6)(7,8)(9,10)(11,12)(15,19)(18,20);(1,2,3,4)(6,8)(10,12)(14,17)(18,20);(2,4)(5,6,7,8)(9,10)(11,12)(13,15,16,19)(14,18,17,20);(13,14)(15,20)(16,17)(18,19);(1,2)(3,4)(5,6)(7,8)(13,14)(15,20)(16,17)(18,19)
