Presentation

minimal degreeμ(G) = 28
transitive degreeμt(G) = 128

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

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