Presentation

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

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

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

Polycyclic presentation:
