Presentation

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

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

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