Presentation

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

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

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

Polycyclic presentation:
