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