Presentation

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

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

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

Polycyclic presentation:
