Presentation

minimal degreeμ(G) = 28
transitive degreeμt(G) = 64

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

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