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

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

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