Just curious, how many digits of π do you have memorized?

Honestly I haven't really bothered going beyond 9 significant digits (3.14159265) since I doubt any manual estimate calculations I have to do involving π would need further precision, plus I know this truncation is rounded off properly (the next truncation that's also rounded off is 3.141592653589793, an extra 7 digits to tackle)

So I know people have talked about optimal first guesses in #Wordle, but are there optimal first guesses for #Nerdle?

Maybe someone can generate all the 8-token equations that comply with Nerdle's rules and perform some info theory analysis on them

Random idea for a game (partially inspired by #wordle):

Give the player a limited number of guesses to figure out a mystery finite set of integers \(S=\{n_1,\ldots,n_k\}\), given \(k = |S|\) and hint indicators for each guess \(S_j\):

- for each \(n_i\in S\), whether \(n_i \in S_j\);
- if all \(n_i \in S_j\), whether \(S=S_j\) or \(S\subsetneq S_j\)

Prior non-final guesses could be infinite sets to whittle down the possibilities, e.g. \(\{3n:n\in\mathbb{Z}\}\)
