Presentation

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

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

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

Polycyclic presentation:
