Presentation

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

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

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