| contents | A reduction of properties (invariants) of compact sets of real numbers to properties of countable orders is presented here. Discussed here is also an embedding property of some compact sets that are called t$\mathbb R$-sets. Among others, it is proved that there are exactly $ω_1$ many non-homeomorphic t$\mathbb R$-sets. |
