Presentation

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

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

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