Presentation

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

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

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

Polycyclic presentation:
