Presentation

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

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

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