Presentation

minimal degreeμ(G) = 28
transitive degreeμt(G) = 128

A minimal faithful permutation representation — 5 generators on 28 points:

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