Presentation

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

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

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

Polycyclic presentation:

2^8|a^2=f,b^2=e,e^2=g,f^2=h,b^a=be,d^a=dh,e^a=eg,c^b=ch,d^b=dg
