Presentation

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

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

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