Presentation

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

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

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

Polycyclic presentation:
