Presentation

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

A minimal faithful permutation representation — 6 generators on 28 points:

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