Presentation

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

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

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