Presentation

minimal degree	μ(G) = 24
transitive degree	μ_t(G) = 256

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

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

Polycyclic presentation:

2^9|a^2=h,b^2=e,c^2=f,f^2=h,g^2=hi,b^a=be,c^a=cf,d^a=de,f^a=fh,g^a=gi,c^b=cg,f^b=fi,g^b=ghi,g^c=gh
