Presentation

minimal degreeμ(G) = 28
transitive degreeμt(G) = 64

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

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