Presentation

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

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

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