Presentation

minimal degreeμ(G) = 24
transitive degreeμt(G) = 128

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

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

Polycyclic presentation:

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