Presentation

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

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

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

Polycyclic presentation:

2^10|a^2=f,b^2=e,d^2=h,f^2=ij,g^2=j,i^2=j,b^a=bg,c^a=cf,c^b=ce,d^c=dh,e^a=ej,f^c=fi,g^a=gj,g^c=gj,i^c=ij
