Presentation

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

A minimal faithful permutation representation — 5 generators on 24 points:

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

Polycyclic presentation:

2^8|a^2=g,b^2=h,c^2=g,e^2=f,b^a=bf,d^a=df,c^b=cf
