Presentation

minimal degree	μ(G) = 20
transitive degree	μ_t(G) = 128

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

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

Polycyclic presentation:

2^9|a^2=f,b^2=g,d^2=i,e^2=i,f^2=i,b^a=bd,c^a=ce,d^a=dh,e^a=ehi,d^b=di,e^b=eh,f^b=fhi,d^c=dh,e^c=ei,f^c=fh
