Presentation

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

A minimal faithful permutation representation — 4 generators on 28 points:

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