Presentation

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

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

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

Polycyclic presentation:

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