Presentation

minimal degreeμ(G) = 21
transitive degreeμt(G) = 96

A minimal faithful permutation representation — 4 generators on 21 points:

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