Presentation

minimal degreeμ(G) = 20
transitive degreeμt(G) = 128

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

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

Polycyclic presentation:
