Presentation

minimal degreeμ(G) = 28
transitive degreeμt(G) = 256

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

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