Presentation

minimal degreeμ(G) = 24
transitive degreeμt(G) = 64

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

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

Polycyclic presentation:

2^10|b^2=i,d^2=j,b^a=bi,d^a=df,d^b=dg,d^c=de,e^a=ej,e^b=eh,f^b=fi,f^c=fj,g^a=gi,g^c=ghj,g^e=gj,h^d=hj
