Yes, I replied to Gordon with this, I think it's a bug in the documentation of `DigraphHomomorphism` which doesn't really explain what the output is.

Same goes for `DigraphIndependentSetsAttr` this does not exist either.

Thanks @ChrisJefferson ! Sorry I didn't reply earlier, somehow overlooked this. Here's some more info, I can reproduce this using the following: ~~~ gap> D := ChainDigraph(3 * 10 ^...

It's here: https://github.com/digraphs/Digraphs/blob/main/azure-pipelines.yml @DanielPointon

Also rebased this onto main and force pushed, this should fix the ci.

Thanks @DanielPointon I think we can ignore the code coverage, unless you can see some places to add tests that test some lines that aren't tested, if you can, them...

@DanielPointon I started reviewing this but realised that there are a few issues, and so I fixed compile warnings in digraphs in general in #633, and hoped you could rebase...

Unfortunately, the changes in this PR appear to leak memory, here's the output of valgrind: [mem_leak.txt](https://github.com/digraphs/Digraphs/files/14872111/mem_leak.txt) Thanks to @Joseph-Edwards for running valgrind. I will fix this.

Awesome thanks @DanielPointon and @Joseph-Edwards !

I just rebased this (and squashed it) on to the current main branch, this was more or less difficult, and so might contain some mistakes!
