Presentation

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

A minimal faithful permutation representation — 4 generators on 28 points:

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