Presentation

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

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

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