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