Presentation

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

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

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