Presentation

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

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

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