Presentation

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

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

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

Polycyclic presentation:

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