Presentation

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

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

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