Presentation

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

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

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