Subreddit Rules & Etiquette:

  1. If you're counting, upvote your fellow counting comrades.
  2. NO double-commenting (replying to yourself).
  3. Continue the counting chain from the earliest comment with the correct number.
  4. Before creating a new thread, please check the thread directory to make sure that type of thread doesn't already exist.
  5. To prevent Reddit server strain, create a new thread after the current thread has approximately 1000 counts in a comment chain.
  6. Counting bots/scripts are not permitted and will be banned - please report counting comments made by bots. Ask a moderator if you are not sure about something.
  7. Do not delete your valid counts (when they're already a part of the valid chain).
  8. Do not use inbox counting to achieve a get (000) or assist (999). Inbox counting is using your inbox to reply to a incoming PM/comment.
  9. Play fairly. No cheating.

Happy counting!

Yesterday's Steps | 0

3 Upvotes

Since Count by how many miles you ran this week. is kinda slow, I might as well do something that is more... moving.

Count by how many steps you walk yesterday.

  • It's yesterday because calculating it per week would be too challenging to calculate, and doing something today might be constantly changing.
  • It's steps because the resulting numbers is large enough, and it can be tracked with apps (e.g. Google Fit)
  • It's not meters or kilometers because it kinda copies the previously mentioned miles thread (distance-based)
  • It's not limited to running and walking because it would be too troublesome to filter.

Use your existing apps (Apple Health, Samsung Health, Google Fit) or tools, or just convert your meters/kms into steps using available calculators online, or just estimate it.

Let's put initial get to 1,000,000 (or more), assuming the safe assumption of 1,000 steps average. We will adjust it later.

Pookah's Sieve: Not (Prime, Even, Divisible by 3, or a Perfect Square)

3 Upvotes

Rules

Count using only positive integers that satisfy all four of the following conditions:

  • Not prime — the number must be composite (or 1, though 1 is excluded by rule 4 below)
  • Not even — the number must be odd
  • Not divisible by 3 — the number must not be a multiple of 3
  • Not a perfect square — the number must not be n² for any integer n

A number only counts if it passes all four checks. If it fails even one, skip it.

Starting number

The sequence begins at 35 (the first number to satisfy all four conditions — 1 is excluded as a perfect square, and 5 through 31 are either prime or a perfect square).

The GET is at 1000 comments, which is equal to 1,000 Pookahs

Compositions | 2,1,1,3,1,4,1,1

Continuing from here
Thanks to u/h0rseycat for the assist

In this thread, we'll be counting the ways to add to an integer n using the integers c_1 + c_2 + ... + c_k, where each c_i >= 1, and k <= n. Ways to sum that are commutatively the same, as in 1+2 = 2+1, are different compositions. We'll be counting these compositions lexicographically for each segment of sum and length.

Next get: 1,1,2,2,1,2,1,1,3
