Presentation

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

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

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