Presentation

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

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

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