Presentation

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

A minimal faithful permutation representation — 5 generators on 20 points:

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

Polycyclic presentation:
