We develop two new strictly equivariant layers with reduced complexity $\mathcal{O}(CL^4)$ and $\mathcal{O}(CL^3 \log L)$, making larger, more expressive models computationally feasible.

However, they produce reconstructed inter\-ferometric images that are limited in quality and scalability for big data.
