Presentation

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

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

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

Polycyclic presentation:
