Presentation

minimal degreeμ(G) = 20
transitive degreeμt(G) = 32

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

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