Presentation

minimal degreeμ(G) = 24
transitive degreeμt(G) = 32

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

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

Polycyclic presentation:

2^10|a^2=i,b^2=g,f^2=j,b^a=bf,c^b=ce,d^c=di,e^a=eh,e^b=ei,e^d=ej,f^b=fij,f^c=fh,g^a=gi,g^c=gi,g^e=gj,g^f=gj,i^b=ij
