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

Polycyclic presentation:

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