Presentation

minimal degreeμ(G) = 24
transitive degreeμt(G) = 128

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

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

Polycyclic presentation:

2^10|a^2=f,b^2=fgij,c^2=e,g^2=i,h^2=j,b^a=bg,c^a=cghj,d^a=dj,d^b=di,e^a=ej,f^b=fi,f^c=fi,g^b=gi,g^c=gi,h^a=hj
