Presentation

minimal degreeμ(G) = 20
transitive degreeμt(G) = 256

A minimal faithful permutation representation — 8 generators on 20 points:

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