Presentation

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

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

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