How about a factorial-based number system? The digits are weighted 1, 2, 6, 24, ...
So 20(!)

Wait, I'm confused.

I understand the progression in the weighting you mentioned (the number to be multiplied by the previous number), but where did 20 come from?

*is ashamed*

Honestly, I still don't get it :/ I've never come across that method of factorials before. Only the progression you mentioned; so 1!=1, 2!=(1x2)=2, 3!=(1x2x3)=6, 4!=(1x2x3x4)=24.

Sorry @ljfa :(

It's simple really.
Next number is six, that is 100(!). One times six + zero times two + zero times one. You just weight the digits from right to left with the factorials.

...OH!

So the factorials are the numeric bases! So instead of for, for example, binary where the digits are 8|4|2|1, so decimal 10 is 1010, in this case the digits are the factorials - 24|6|2|1, right?

So in that case, the maximum value in each digit is the n!, so for the 3rd digit (sixes), the highest that can be is 3, and for the 4th digit (twenty-fours) the highest that can be is 4? And the 5th digit is 120s... let me just... hang on.

4x24 + 3x6 + 2x2 + 1x1 = 119...

Son of a gun it works!!! :D

In that case...

101(!)
