Presentation

minimal degreeμ(G) = 20
transitive degreeμt(G) = 256

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

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

Polycyclic presentation:
