Presentation

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

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

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

Polycyclic presentation:
