Presentation

minimal degreeμ(G) = 24
transitive degreeμt(G) = 64

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

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