“…In the last period, the study of perfect codes in graphs was primarily focused on their existence and construction in some central families of graphs. Many researches were done on standard graph products and product-like graphs [2,23,28,39,42,44]. Among other classes of graphs on which perfect codes were investigated we mention Sierpiński graphs [8,27], cubic vertex-transitive graphs [31], circulant graphs [10], twisted tori [24], dual cubes [25], and AT-free and dually chordal graphs [4].…”
