Presentation

minimal degree	μ(G) = 20
transitive degree	μ_t(G) = 64

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

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

Polycyclic presentation:
