Presentation

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

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

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

Polycyclic presentation:
