Presentation

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

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

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