Presentation

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

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

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