Presentation

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

A minimal faithful permutation representation — 4 generators on 20 points:

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