Presentation

minimal degree	μ(G) = 24
transitive degree	μ_t(G) = 64

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

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

Polycyclic presentation:

2^11|d^2=e,c^a=ci,c^b=cg,d^a=dh,d^b=df,d^c=de,e^a=ek,e^b=ej,f^d=fj,g^d=gj,h^d=hk,i^d=ik
