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