Greetings @zari!
You’ve got some wonderful advice already here- while it’s an interesting topic, I’m afraid I don’t use numerology much myself (I joke that I still have nightmares about high school math class lol 
).
Numbers aren’t usually my thing, but I know there are others in the forum who have shared their number magick in the past. Perhaps something in the following discussions will be interesting for you:
- Numerology basics
- Card set numerology
- Numerology: Good/Bad Numbers
- Recommended Numerology Books
- 11-11 Portal
- Letter F and Number 6
In terms of geometry and shape magick, I know @mary25 recently shared a great post about Palindromes (specifically, palindrome words and names) that you may enjoy!
Good luck and blessed learning, @zari!
