Presentation

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

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

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