Presentation

minimal degreeμ(G) = 20
transitive degreeμt(G) = 64

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

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