Presentation

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

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

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