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