Presentation

minimal degreeμ(G) = 23
transitive degreeμt(G) = 224

A minimal faithful permutation representation — 4 generators on 23 points:

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