Presentation

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

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

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

Polycyclic presentation:
