Presentation

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

A minimal faithful permutation representation — 4 generators on 28 points:

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