Presentation

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

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

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

Polycyclic presentation:
