If 14^2 = 196, does that mean 41^2 = 691?

i think this holds for any numbers that are built out of up to three 1s in a row and either to two 2s in a row or one 3.

e.g.
112^2 = 12544
211^2 = 44521
11122^2 = 123698884
22111^2 = 488896321
1113*1113 = 1238769
3111^2 = 9678321
you can see how it works out if you do the multiplication by hand -- it basically boils down to avoiding having to carry any ones when you sum the right piece's product and the left piece's product

Is that an exhaustive list of numbers for which it holds?

Sorry Anon, I'm just shitposting, don't take it seriously.
I don't have the time right now to do it myself, but this Anon >>12917374 is on a good track. You can generalize this by expressing the numbers as powers of ten and equation the right coefficients.
Keep an open mind and practice, then you'll definitely make it, fren.
