Presentation

minimal degreeμ(G) = 28
transitive degreeμt(G) = 512

A minimal faithful permutation representation — 4 generators on 28 points:

(1,2)(3,4);(13,14,16,19,17,21,24,27,18,20,25,26,15,22,23,28);(2,4)(5,6,8,7,9,10,12,11)(14,19,20,26)(15,17)(16,24)(21,28,22,27)(23,25);(5,7,8,10,9,11,12,6)(13,15,18,17)(16,24,25,23)(19,26)(27,28)

Polycyclic presentation:

2^10|b^2=f,c^2=e,d^2=ej,e^2=h,f^2=i,i^2=j,c^a=cg,c^b=cfij,d^b=dij,d^c=dhj,e^b=ej,f^c=fi,f^d=fj,i^c=ij
