Presentation

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

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

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

Polycyclic presentation:
