Presentation

minimal degreeμ(G) = 20
transitive degreeμt(G) = 512

A minimal faithful permutation representation — 5 generators on 20 points:

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

Polycyclic presentation:

2^10|c^2=gi,d^2=ghij,b^a=bg,c^b=cgh,d^a=dhj,d^b=dgj,e^a=ef,e^b=ef,e^c=efhi,e^d=efhi
