   Format: MarkdownItexI felt like we had an entry on Z-categories, but maybe we don't. We do have *[[combinatorial spectra]]*, and I have added cross-links. <a href="https://ncatlab.org/nlab/revision/diff/%28%E2%88%9E%2CZ%29-category/2">diff</a>, <a href="https://ncatlab.org/nlab/revision/%28%E2%88%9E%2CZ%29-category/2">v2</a>, <a href="https://ncatlab.org/nlab/show/%28%E2%88%9E%2CZ%29-category">current</a>
