Presentation

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

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

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

Polycyclic presentation:

2^10|b^2=gh,c^2=h,f^2=j,b^a=bg,c^a=cg,c^b=cghi,d^b=dhi,e^b=egh,f^a=fj,f^c=fj
