Presentation

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

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

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