Presentation

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

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

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