Presentation

minimal degreeμ(G) = 20
transitive degreeμt(G) = 32

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

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