Presentation

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

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

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

Polycyclic presentation:
