Presentation

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

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

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