Presentation

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

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

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