Presentation

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

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

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

Polycyclic presentation:

2^10|a^2=e,b^2=g,c^2=e,d^2=h,f^2=i,h^2=i,i^2=j,c^b=cg,d^a=df,d^c=di,e^d=ej,f^a=fi,f^c=fj,h^a=hi,h^c=hj,i^a=ij
