Presentation

minimal degreeμ(G) = 24
transitive degreeμt(G) = 64

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

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

Polycyclic presentation:

2^9|a^2=e,c^2=gh,d^2=g,f^2=i,b^a=bd,d^a=df,f^a=fh,g^a=gi,h^a=hi,d^b=dg,e^b=efgi,f^b=fi,e^d=ehi,f^e=fi
