Presentation

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

A minimal faithful permutation representation — 5 generators on 28 points:

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