Presentation

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

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

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