Presentation

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

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

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