Presentation

minimal degreeμ(G) = 20
transitive degreeμt(G) = 32

A minimal faithful permutation representation — 5 generators on 20 points:

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

Polycyclic presentation:
