Presentation

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

A minimal faithful permutation representation — 6 generators on 20 points:

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