Presentation

minimal degreeμ(G) = 20
transitive degreeμt(G) = 256

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

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

Polycyclic presentation:

2^10|a^2=f,e^2=fh,b^a=bg,c^a=cfj,c^b=ci,d^a=dfj,e^a=eh,e^c=efgi,e^d=efj
