Presentation

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

A minimal faithful permutation representation — 5 generators on 28 points:

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