Presentation

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

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

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

Polycyclic presentation:
