Presentation

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

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

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