Presentation

minimal degree	μ(G) = 20
transitive degree	μ_t(G) = 64

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

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

Polycyclic presentation:

2^10|a^2=d,b^2=dei,d^2=i,e^2=i,f^2=hj,g^2=i,h^2=j,b^a=bf,c^a=cg,c^b=ch,d^b=dh,d^c=di,e^a=ei,e^b=eh,e^c=ei,f^b=fhi,f^c=fh,f^e=fj,g^b=gh,g^c=gi,h^b=hj,h^c=hj,i^b=ij
