Presentation

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

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

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