Presentation

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

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

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