Presentation

minimal degreeμ(G) = 20
transitive degreeμt(G) = 32

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

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

Polycyclic presentation:

2^10|a^2=d,b^2=g,f^2=j,b^a=be,c^a=cefj,c^b=cg,d^b=dh,d^c=di,e^a=eh,e^b=eh,e^c=ei,f^a=fhi,f^b=fi,f^c=fi,f^e=fj,g^a=gh,g^f=gj,h^c=hj,i^b=ij
