Presentation

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

A minimal faithful permutation representation — 5 generators on 24 points:

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

Polycyclic presentation:

2^10|b^2=f,c^2=f,d^2=g,g^2=i,i^2=j,d^a=dh,d^b=dg,d^c=di,e^a=eh,e^d=eh,f^d=fj,g^b=gi,g^c=gj,i^b=ij
