Presentation

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

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

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