Presentation

minimal degreeμ(G) = 20
transitive degreeμt(G) = 256

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

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

Polycyclic presentation:

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