Presentation

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

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

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

Polycyclic presentation:
