Presentation

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

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

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

Polycyclic presentation:

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