Presentation

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

A minimal faithful permutation representation — 7 generators on 28 points:

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