Presentation

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

A minimal faithful permutation representation — 6 generators on 20 points:

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

Polycyclic presentation:

2^10|a^2=g,e^2=ij,f^2=j,d^a=dg,d^b=dgh,d^c=dgh,e^a=ei,e^b=eij,f^a=fj,f^c=fj,f^d=fj
