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