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

Polycyclic presentation:

2^9|a^2=f,b^2=g,c^2=f,f^2=h,g^2=i,b^a=be,d^a=dehi,c^b=cei,d^c=dh
