Presentation

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

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

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

Polycyclic presentation:

2^8|a^2=e,b^2=g,c^2=fgh,d^2=g,e^2=h,b^a=bd,c^a=cfh,d^a=df,d^b=dg,e^b=efg
