Presentation

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

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

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

Polycyclic presentation:

2^8|a^2=e,b^2=f,d^2=g,e^2=h,b^a=bd,c^a=ch,f^a=fg,e^b=eg
