Presentation

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

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

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