Presentation

minimal degreeμ(G) = 20
transitive degreeμt(G) = 64

A minimal faithful permutation representation — 3 generators on 20 points:

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