Presentation

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

A minimal faithful permutation representation — 4 generators on 20 points:

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

Polycyclic presentation:

2^9|a^2=f,b^2=g,c^2=ef,f^2=h,g^2=i,b^a=be,d^a=dhi,c^b=ch,d^c=dhi
