Presentation

minimal degreeμ(G) = 24
transitive degreeμt(G) = 32

A minimal faithful permutation representation — 3 generators on 24 points:

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