Presentation

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

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

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