Presentation

minimal degree	μ(G) = 24
transitive degree	μ_t(G) = 128

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

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

Polycyclic presentation:

2^9|a^2=f,b^2=dfh,d^2=gh,e^2=gh,f^2=i,b^a=bd,c^a=ce,d^a=dg,d^b=dh,e^b=egh,f^b=fh,d^c=dgh,e^c=egh,f^c=fgh
