My University has only provided a word template for my thesis and I am required to try to adapt the LaTeX style as close as possible to the template. I'm having a bit of trouble with the Chapter heading formatting. It would need to look as close as possible to the image: with the text centered on the page horizontally and vertically, the number bigger than the chapter name and without the word "Chapter". Also important that it doesn't affect the tiles of the table of contents, list of figures etc as those are different.
I would provide MWE, but I'm not sure it's relevant in this case.
Thank you in advance!
