Presentation

minimal degreeμ(G) = 20
transitive degreeμt(G) = 64

A minimal faithful permutation representation — 4 generators on 20 points:

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

Polycyclic presentation:
