   Format: MarkdownItexAdded an analogous proposition to that added on the page for [[split monomorphism]]. However, it's not clear to me that having both pages is helpful, since they are essentially duplicates of one another. <a href="https://ncatlab.org/nlab/revision/diff/split+epimorphism/14">diff</a>, <a href="https://ncatlab.org/nlab/revision/split+epimorphism/14">v14</a>, <a href="https://ncatlab.org/nlab/show/split+epimorphism">current</a>
