Presentation

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

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

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