Presentation

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

A minimal faithful permutation representation — 3 generators on 28 points:

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