Presentation

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

A minimal faithful permutation representation — 3 generators on 20 points:

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

Polycyclic presentation:

2^9|a^2=f,b^2=dfh,c^2=ei,f^2=hi,g^2=i,b^a=bd,c^a=ce,d^a=dg,g^a=gh,d^b=dgi,f^b=fgi,g^b=gh,h^b=hi,f^d=fhi,g^d=gi
