Presentation

minimal degreeμ(G) = 28
transitive degreeμt(G) = 256

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

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