Presentation

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

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

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

Polycyclic presentation:
