Abstract: It is proved that any non-normable Fréchet space with a semi-symmetric absolute basis is isomorphic to the space $ \omega$ of all scalar sequences. A similar result is shown for quasi-homogeneous absolute bases. It is also proved that any nuclear Fréchet space with a semi-subsymmetric basis is isomorphic to $ \omega$.
