Presentation

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

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

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

Polycyclic presentation:

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