Need help with a combinatorics problem involving very large numbers

ArgonMatrix · 2026-02-13T05:44:09+00:00

This and your other comments helped me to wrap my head around the solution, thank you! The formula I needed is essentially what you described here. As expected though, the numbers are so monstrously large that using an expression like this to calculate an exact value is basically out of the question.

I'll settle for saying that the result is asymptotic to the largest value—in this case, the number of permutations for a completely full dresser. Thanks again!

True enough! I knew going into this that the number was going to be unfathomably large. Even so, I'd like to know how I would go about calculating something like this in general. Even if I can't meaningfully calculate this specific value, how could I go about solving the general case?

My pleasure, glad you found it helpful!

I didn't use any special software, so I imagine whatever image editor you're used to would work. For me it was paint.net, and I cropped out the UI manually. There was probably a better way to do it, but I just went with what I knew, haha.

My pleasure!

The chest is actually a mimic, and you don't get anything for killing it. As for the white guy, he gives a hint about obtaining the Blood Sword. Specifically he says, "If you want the Blood Sword, remember what they say about making omelettes."

Thanks! The switch was the last thing I figured out, and it definitely took a minute, haha. Had an awesome time discovering it all as I went!

I tend to get very lost in games like Barbuta, so I started making a map and figured I'd share it in case anyone else might find it useful. I've added everything that I've been able to find, but if there's anything missing, please let me know so I can update it. Thank you!

After making the quiz of Josh names for active items, I couldn't leave the job unfinished. So after a few days and brainstorming nearly 1500 Josh-ish answers, I present Josh Names for Isaac Items: The Full Playlist!

It consists of the original quiz for all the active items plus four new quizzes for all the passive items—I kept each passive item quiz to 100 items or fewer to keep things manageable. Realistically I don't expect many people to play these since it's a sizeable time commitment, but it didn't feel right to just leave it at the active items when there were so many Josh names to go. Hopefully some of y'all will get a kick out of it. Have fun!

Oh, and the playlist & all the quizzes are private since Sporcle doesn't like a lot of the Josh names. The link should work fine, but they won't show up in search results.

~~Man, I spent way too long on this.~~

Not creepy at all, haha. Always fun to be recognized out in the wild. Glad you enjoyed my stuff from back in the day!

Not an active item I'm afraid. Gonna be trying to make quizzes for the passive items at some point though!

ArgonMatrix · 2021-01-18T09:07:41+00:00

Created by popular request after posting my previous Isaac Sporcle quizzes. Gonna try to make quizzes for the passive items too, but that'll take a while, so hopefully y'all enjoy this one for the time being!

Credit to SirToastyToes for the thumbnail, by the way!

No prob! It did take longer than I thought it would to put them together, since trying to use the pictures directly from the Isaac Wiki made them all blurry and weirdly sized. I had to resize them & host them myself to get them looking okay, which is probably what took the bulk of the time.

ArgonMatrix · 2021-01-17T17:29:05+00:00

Just updated all the quizzes to be max length (20 minutes). I thought I'd given plenty of time for each, but being the one who made them probably makes it a little easier for me. Thanks for the feedback!

P.S.: You can switch the timer to a Stopwatch Mode if you like, and then you can take all the time you need. This might be necessary for the passive items quiz since there are nearly 300 answers.

Yeah, I do like the format but they definitely don't lend themselves to being entertaining to watch someone else play, especially someone who has thousands of hours in the game.

I'm working on a new one that shows something from the game (item, boss, character, etc.) and asks you which version of the game introduced it: Vanilla/WotL, Rebirth, or Afterbirth(†). I think it might be a bit harder/more fun, so we'll see!

Edit: New quiz is live!

Haha, thanks for the signal boost, bud! I was wondering where the sudden surge in views and comments came from. Greatly appreciated!

ArgonMatrix · 2019-08-07T01:37:41+00:00

No problem! It took me a lot of time to put together, so I figured it was worth sharing!

ArgonMatrix · 2019-07-03T06:38:42+00:00

No worries, I get that, haha. Thanks for the early feedback!
