Presentation

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

A minimal faithful permutation representation — 6 generators on 20 points:

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

Polycyclic presentation:
