Trac #34690: implement more constructions for Hadamard matrices, e.g. for size 116
With #32267 done, the next not yet implemented construction is for n=116. This was originally constructed by Williamson, cf e.g. Marshall Hall's book https://onlinelibrary.wiley.com/doi/book/10.1002/9781118032862 Implementing Williamson construction would be a natural way here.
