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

Polycyclic presentation:
