Presentation

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

A minimal faithful permutation representation — 3 generators on 28 points:

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