Presentation

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

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

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

Polycyclic presentation:

2^9|a^2=g,b^2=h,c^2=g,d^2=fg,e^2=i,b^a=be,c^a=cf,e^a=ei,h^a=hi,d^b=dei,e^d=ei,h^d=hi
