Presentation

minimal degreeμ(G) = 28
transitive degreeμt(G) = 256

A minimal faithful permutation representation — 3 generators on 28 points:

(1,2)(3,4)(5,6,9,11,8,7,12,10)(14,20)(15,24)(16,27)(17,28)(18,21)(22,23)(25,26);(2,4)(9,12)(10,11)(13,14)(15,21)(16,25)(17,24)(18,26)(19,23)(20,27)(22,28);(5,7)(6,8)(9,10)(11,12)(13,15,19,26)(14,21,23,18)(16,22,17,20)(24,27,25,28)
