Presentation

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

A minimal faithful permutation representation — 4 generators on 28 points:

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