Presentation

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

A minimal faithful permutation representation — 5 generators on 20 points:

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