Return an `l`-length sequence of nonnegative integers such that any `n`-length-or-shorter combination of members with repeats allowed can be uniquely identified by its sum.
The optimal solution is the one with the lowest maximum-member.
(If that were "product" instead of "sum", the obvious solution would be the first `l` primes.)
Ich fasse nochmal zusammen:
- die maximal mögliche Anzahl an Kombinationen
- 3x3 grid auf Android
- mindestens 4 Zahlen
- nur gerade Linien
- keine Sprünge, Kombinationen wie 1zu3 sind ungültig, da sie automatisch zu 1-2-3 würden
- eine Zahl darf zweimal besucht werden, wird beim zweiten Mal aber nicht mehr mitgezählt, zB 1-5-9-8-7-(5)-3
- schräg ist erlaubt, zB 1zu6
Frage:
Ist die im Internet kolportierte Zahl von 389.112 möglichen Entsperrmustern korrekt?

At least it was easier to calculate than the last math exam I had in college. Given a parabula ax^2 up to a height h, rotate it around the y axis to make a vase, fill it to half its volume, to what angle can you tilt this vase before the water spills (disregard physical effects)
Question: Is the following statement true (or under which conditions is it true):
\[ \lim_{n \to \infty} f_n(x) = f(x) \implies \lim_{n \to \infty} f_n(g(n)) = \lim_{n \to \infty} f(g(n)) \]

I asked ChatGPT “I have a ten-liter bucket, a five-liter bucket, and 50-milliliter shot glass. How do I use these items to measure a 50-milliliter shot of bourbon?” Its answer was hilariously long and wrong.

#mathproblem Find all positive integers a,b,c such that a^b-b^c = (a+b)^(c-b).
I found two: (2,1,1) and (7,3,5). I have no idea if there are any more.
Equilateral triangle and two squares. Show that the marked points are collinear. #geometry #mathpuzzle #mathproblem
Three congruent squares. Show that the red dashed lines are congruent. #geometry #mathpuzzle #mathproblem
To mark the occasion of my first post, here's a problem I wrote a while back. #geometry #mathpuzzle #mathproblem
#MathProblem if you throw a dice 10 times, and each time let's assume you'll get nr 1 🎲 (10 times in a row). How many times you'll have to flip a coin and get the same side to reach the probability equivalent of throwing a dice with the mark 1, 10 times in a row? @syscrash call your friends :apple_1: 😜
