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