Presentation

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

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

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