Presentation

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

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

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