Presentation

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

A minimal faithful permutation representation — 3 generators on 20 points:

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

Polycyclic presentation:
