Presentation

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

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

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

Polycyclic presentation:
