Presentation

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

A minimal faithful permutation representation — 6 generators on 28 points:

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