Presentation

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

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

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