Presentation

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

A minimal faithful permutation representation — 3 generators on 28 points:

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