Abstract: A dyadic space S is defined to be a continuous image of $ {\{ 0,1\} ^\mathfrak{m}}$ for some infinite cardinal number $ \mathfrak{m}$. We deduce Banach space properties of $ C(S)$ and topological properties of S. For example, under certain cardinality restrictions on $ \mathfrak{m}$, we show: Every dyadic space of topological weight $ \mathfrak{m}$ contains a closed subset homeomorphic to $ {\{ 0,1\} ^\mathfrak{m}}$. Every Banach space X isomorphic to an $ \mathfrak{m}$ dimensional subspace of $ C(S)$ (for S dyadic) contains a subspace isomorphic to $ {l^1}(\Gamma )$ where $ \Gamma $ has cardinality $ \mathfrak{m}$.
