Presentation

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

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

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