Presentation

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

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

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