Presentation

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

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

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