Presentation

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

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

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

Polycyclic presentation:

2^8|a^2=g,b^2=eg,c^2=h,d^2=f,b^a=be,c^a=cf,e^a=eh,e^b=eh,g^b=gh
