Presentation

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

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

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