Presentation

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

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

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