Presentation

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

A minimal faithful permutation representation — 7 generators on 28 points:

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