Abstract

In the following text we compute possible heights of A\mathbb A (Alexandroff square), O\mathbb O (unit square [0,1]×[0,1][0,1]\times[0,1] with lexicographic order topology) and U\mathbb U (unit square [0,1]×[0,1][0,1]\times[0,1] with induced topology of Euclidean plane). We prove Ph(A)={n:n5}{+}P_h(\mathbb{A})=\{n:n\geq5\}\cup\{+\infty\}, Ph(O)={n:n4}{+}P_h(\mathbb{O})=\{n:n\geq4\}\cup\{+\infty\}, Ph(U)={n:n1}{+}P_h(\mathbb{U})=\{n:n\geq1\}\cup\{+\infty\} (where for topological space XX, by Ph(X)P_h(X) we mean the collection of heights of transformation groups with phase space XX. In this way we also prove that there is not any topological transitive (resp. Devaney chaotic) Alexandroff square transformation group.
