Presentation

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

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

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