Presentation

minimal degreeμ(G) = 21
transitive degreeμt(G) = 80

A minimal faithful permutation representation — 3 generators on 21 points:

(1,2,3,5,4)(6,9)(7,14)(8,16)(10,20)(11,21)(12,13)(15,18)(17,19);(6,8)(7,13)(9,17)(10,14)(11,19)(12,18)(15,21)(16,20);(2,3,4,5)(6,7,10,15,12,17,11,16)(8,13,14,21,18,9,19,20)
