Presentation

minimal degreeμ(G) = 24
transitive degreeμt(G) = 256

A minimal faithful permutation representation — 3 generators on 24 points:

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

Polycyclic presentation:

2^8|a^2=g,b^2=fg,c^2=gh,d^2=f,e^2=h,b^a=bd,c^a=ce,d^a=df,e^a=eh,d^b=df,e^b=eg,d^c=dg,e^c=eh
