Presentation

minimal degreeμ(G) = 20
transitive degreeμt(G) = 64

A minimal faithful permutation representation — 3 generators on 20 points:

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

Polycyclic presentation:

2^9|a^2=f,b^2=df,c^2=g,e^2=i,f^2=h,h^2=i,b^a=bd,c^a=ce,d^a=dg,g^a=gi,c^b=ch,d^b=dg,f^b=fg,g^b=gi,f^c=fi,f^d=fi
