Presentation

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

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

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