Presentation

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

A minimal faithful permutation representation — 5 generators on 28 points:

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