Presentation

minimal degree	μ(G) = 20
transitive degree	μ_t(G) = 128

A minimal faithful permutation representation — 3 generators on 20 points:

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

Polycyclic presentation:
