Presentation

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

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

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

Polycyclic presentation:

2^8|d^2=e,f^2=gh,g^2=h,b^a=be,c^a=cf,f^a=fg,g^a=gh,f^c=fg,g^c=gh
