Presentation

minimal degreeμ(G) = 20
transitive degreeμt(G) = 128

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

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

Polycyclic presentation:

2^9|a^2=h,b^2=ehi,e^2=i,h^2=i,b^a=be,c^a=cf,d^a=dg,e^b=ei,h^b=hi
