Presentation

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

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

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