Presentation

minimal degreeμ(G) = 28
transitive degreeμt(G) = 128

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

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