Presentation

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

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

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

Polycyclic presentation:
