Presentation

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

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

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

Polycyclic presentation:

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