Presentation

minimal degree	μ(G) = 20
transitive degree	μ_t(G) = 256

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

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

Polycyclic presentation:
