Presentation

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

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

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

Polycyclic presentation:

2^9|a^2=g,b^2=egh,e^2=h,f^2=i,g^2=h,b^a=be,c^a=cf,d^a=dh,d^b=dh,e^b=eh,f^b=fi,g^b=gh,d^c=dh,e^c=ei,f^c=fi,g^c=gi
