Presentation

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

A minimal faithful permutation representation — 4 generators on 28 points:

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