Presentation

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

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

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