Presentation

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

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

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

Polycyclic presentation:

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