Presentation

minimal degreeμ(G) = 20
transitive degreeμt(G) = 128

A minimal faithful permutation representation — 6 generators on 20 points:

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