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

Polycyclic presentation:

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