Presentation

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

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

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