Maybe start by learning the correct terms for the things you're supposedly interested in, as well as how to spell them, then go and ask on /x/ rather than /lit/.

Start with Euclid's Elements

sorry for any spelling horrors, i came to lit couse i want something more serius abour (an study about their presence in history maybe?). anywhere i find something interesting i just end up with "iniciation" and stuff like that.

Mario Livi wrote a book on the Golden Ratio and (I think) Fibonacci. He maybe presses his case too far sometimes, but he might lead to other sources for you.

Stop being a butt.

Take your pseudoscience to /x/.

>>7608869
im not interesting in the "pseudoscience" aspects of it (thatss the whole point for not asking on /x/). i want the more mathematical aspects of it (just curiosity, like studing symbols). i dont like the "mystic" aspect of this stuff, just interest in the mathematics and geometry behind it

>>7608865
thanks, i will start with it, any other recomendation will be apreciated

You don't really need any abstract maths for this. There's things like Group Theory and the study of Symmetries but those aren't going to help you understand much - it's pretty abstract and is more about classifying and doing mathematics with symmetry relations, not the aesthetics of the thing.
The closest I can think of that might be of interest are Kabbalah texts like the Hekhalot books. Maimonides also wrote something on the hierarchy of angels(which again ties into the Sephiroth) which you might also like. /x/ probably knows more about this kind of stuff, you should also ask there.
There's also some parts of the Divine Comedy that deal with the shape and symmetry of Hell, Purgatory and Heaven, but they're by no means the focus of the work.
