Fair warning: this comment is super mathy. Don't progress further unless you care for math.

Also some of the stuff I say may have already been discussed in some math theory course you've taken, but I haven't seen this before myself so I dunno if any of you guys have either.

So I was just sorta screwing around with numbers and stuff, and I figured out that there's a pattern if you add the digits in the multiples of numbers until you reach a single-digit number (for example, 7x8=56, 5+6=11, 1+1=2), and the pattern indefinitely repeats, like a giant repeating times table. Then I figured out that if you continuously add the digits for square numbers like that, you'll always get 1, 4, 7, or 9, which is weird because 1, 4, & 9 are square, but seven isn't.

In this pattern you may notice small patterns such as increasing by ones in the one's column, going through the even then odd numbers in the twos column, and others. Also, you may notice that the 1 and 8 columns are reverses of each other, similarly with the 2 & 7, 3 & 6, and 4 & 5.

I also similarly expressed thoughts about this in these tweets to YouTuber Numberphile, where I also made a chart demonstrating the original pattern:
