Presentation

minimal degreeμ(G) = 20
transitive degreeμt(G) = 64

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

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

Polycyclic presentation:

2^10|e^2=g,f^2=h,e^c=ei,e^d=eg,f^a=fg,f^b=fh,f^c=fj,f^d=fh,f^e=fj
