So what do we do when we get to base 10? Do we use A, B, C, etc? No: Numbers larger than about 3.6 million are simply illegal.

Finally, a system that uses more information to express less information.
According to this article, the factoradical system gets efficient for numbers larger than 20!, but i guess this here is a shining example of
less ismore is lessIt begins to improve related to regular base-10 after, well, 10!, but it takes a while to recover for lower base numbers before that.
I fell like this one really needs the explainxkcd and I still don’t get it 🤣
The idea is, each number is expressed as a sum of n factorials, with n being the number of digits in the number post-conversion. You start with the highest factorial that you can subtract out of the original number and work your way down.
1 becomes 1, because 1 = 1!, so the new number says “1x(1)”.
2 becomes 10, because 2 = 2!. The new number says “1x(2x1) + 0x(1)”.
3 becomes 11, because it’s 2 + 1. The new number says “1x(2x1) + 1x(1)”.
21 becomes 311: 4! is 24, so that’s too big, so we use 3!, which is 6. 3x6 = 18, so our number begins as 3XX.
That leaves 3 left over, which we know is 11. The new number says “3x(3x2x1) + 1x(2x1) + 1x(1)”.I appreciated them correcting Randall’s bad alt-text math - he was off by a power of ten!
Good grief, it’s far too early in the morning for this sort of thing. My brain hurts now.
This is cursed, haha
What’s the point of such a system ?
Hum… Have you checked what site it’s on?
This is actually a pretty cool idea.
0 = 0
1 = 1
2 = 10
3 = 11
4 = 20
5 = 21
6 = 100
101, 110, 111, 120, 121,
200, 201, 210, 211, 220, 221, 300, 301…
