Presentation

minimal degree	μ(G) = 24
transitive degree	μ_t(G) = 512

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

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

Polycyclic presentation:

2^10|a^2=h,b^2=e,d^2=fgi,e^2=i,h^2=j,b^a=bhj,c^a=ch,d^a=df,d^b=dfg,h^b=hj,h^c=hj
