Presentation

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

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

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