Presentation

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

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

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

Polycyclic presentation:

2^10|a^2=g,b^2=hij,e^2=j,b^a=bg,c^a=cf,c^b=ce,d^a=di,d^b=dj,e^a=eh,e^c=ej,f^a=fi,f^b=fhij,f^e=fj,g^c=gi,h^c=hj
