Presentation

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

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

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

Polycyclic presentation:

2^8|a^2=h,b^2=eg,d^2=f,b^a=be,c^a=cf,d^a=de,c^b=cg
