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)(7,12,13,16)(8,14)(10,17)(11,18,19,20)(15,21);(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)(10,13)(12,17)(14,20)(15,19)(18,21)
