Presentation

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

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

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