Presentation

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

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

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