Presentation

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

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

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