Presentation

minimal degreeμ(G) = 24
transitive degreeμt(G) = 128

A minimal faithful permutation representation — 5 generators on 24 points:

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

Polycyclic presentation:

2^10|a^2=g,b^2=f,c^2=fg,d^2=g,e^2=h,h^2=i,i^2=j,c^a=cg,c^b=cg,d^b=dg,e^b=ei,e^c=eh,f^e=fj,h^b=hj,h^c=hi,i^c=ij
