Presentation

minimal degreeμ(G) = 28
transitive degreeμt(G) = 64

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

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