Presentation

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

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

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