Presentation

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

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

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

Polycyclic presentation:
