Presentation

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

A minimal faithful permutation representation — 6 generators on 20 points:

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

Polycyclic presentation:

2^9|a^2=gh,b^2=g,d^2=h,b^a=bg,c^a=ch,f^a=fi,c^b=ci,d^c=dh,e^c=ei
