Presentation

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

A minimal faithful permutation representation — 6 generators on 28 points:

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