Presentation

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

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

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