Presentation

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

A minimal faithful permutation representation — 3 generators on 24 points:

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

Polycyclic presentation:

2^8|a^2=h,c^2=h,d^2=g,e^2=h,b^a=bd,c^a=ce,d^a=dg,e^a=eh,f^a=fg,c^b=cf,d^b=dg,d^c=dg,e^c=eh
