Presentation

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

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

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