Presentation

minimal degreeμ(G) = 28
transitive degreeμt(G) = 256

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

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