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

Polycyclic presentation:
