Presentation

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

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

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