Pascal's triangle seems to follow a pattern.
row ≤ 5, but
161051. However if you used Base100, you could go further.
So, my conjecture is that
11row-1 will be equal to the corresponding row in Pascal's Triangle, given that all calculations are done without a Base. For example,
116-1 would return
I asked my teacher about this, and we argued about it, him saying that it would have to break at some point, but I argued that it couldn't, it had no base, so there would never be carrying over, and thus no discrepancies.
