Presentation

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

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

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