Presentation

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

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

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