Presentation

minimal degreeμ(G) = 24
transitive degreeμt(G) = 256

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

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

Polycyclic presentation:

2^8|a^2=f,b^2=eg,c^2=h,d^2=e,f^2=h,b^a=be,c^a=cf,d^a=de,c^b=cg,f^c=fh
