Presentation

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

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

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

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,d^a=dh,c^b=ch
