Presentation

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

A minimal faithful permutation representation — 4 generators on 24 points:

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

Polycyclic presentation:

2^10|a^2=e,b^2=g,c^2=ehi,h^2=i,i^2=j,c^a=ch,c^b=cg,d^c=df,e^c=ej,h^a=hi,h^c=hj,i^a=ij
