Presentation

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

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

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

Polycyclic presentation:

2^9|a^2=i,b^2=fi,c^2=g,d^2=f,e^2=gh,b^a=bf,c^a=cg,d^a=df,c^b=ch
