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

Polycyclic presentation:
