Presentation

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

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

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