Presentation

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

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

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