Presentation

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

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

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