Presentation

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

A minimal faithful permutation representation — 5 generators on 28 points:

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