Presentation

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

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

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