@rglullis @Rooki (OT: the last paragraph in the post has a couple of typos. I believe it should be TINSTAAFL (also I recommend making it an abbr for the less informed), and there is an “under” that should probably be “understand”)

I only just found this but, in case you're still testing things, here's a couple of hints:

  1. it is possible to navigate in the dark;
  2. it is possible to climb even without stairs, so you can usually get out of subterranean pits even tool-less; it's extremely rare to get into an actual “save-ender” situation
  3. as your tech level progresses, you'll discover ways to automate most things;
  4. do focus on getting ore; there are hints in the rock to where it may be.

@TootSweet this reminds me of https://github.com/philipl/pifs, the filesystem based on the normality of π

@mrdk @mathematics @math@lemmy.ml @math@kbin.social also this might explain why @mau saw some relation to Gray codes in the binary case.

oh, interesting. It's definitely related, although we allow different substrings to start at the same place, and this has a huge impact on the lengths (also it's not cyclic in our case, but that probably makes things worse).

A curious math problem I came up with: given a target, what's the fewest digits an integer must have (in a given base) to contain all integers from 0 to the target, as substrings?

@mathematics @math@lemmy.ml @math@kbin.social

e.g. for a target of 19 a candidate representative would be 1011213141516171819 in base 10, that has 19 digits. Can it be done in less, or is $\sigma_10(19) = 19$?
Can we find a general rule? Any properties of this function?

@SuperSynthia @dvdnet62 I'll explain in two very simple words.
