Maybe it is. Feynman’s abacus story suggests that he (and colleagues) were familiar with lots of specific numbers and that it matters, somehow. Perhaps I should pick up the habit. Or perhaps that’s backwards, and there’s some particularly useful skill tree that, as a side effect, results in learning to recognize lots of numbers. Either way, just knowing that this is a common thing among the mathematically inclined is worth knowing.

If I had to guess, I’d guess that the largest contributor towards viewing numbers like that was probably my courses taught from https://www.amazon.com/Discrete-Combinatorial-Mathematics-Applied-Introduction/dp/0201199122/ in university.
