Presentation

minimal degreeμ(G) = 24
transitive degreeμt(G) = 256

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

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

Polycyclic presentation:
