Presentation

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

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

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