Presentation

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

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

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