Presentation

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

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

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