Presentation

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

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

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