This sequence can have ambiguity solution. One leads to the right answer. The other not. Based on a[1,11,21,1211,111221,

I got this: let a:'1' , b:'11' , c:'2' . after a sequence step, a changes to b ; b divides into c, a ; and c divides into a,c ; with this pattern, a[0]=='11'=='a' , a[1]=='11'=='b', a[2]=='21'=='ca' , a[3]=='1211'=='ac'+'b' , a[4]=='111221'=='b'+'ac'+'ca' ; you see it fits the broken sequence

it leads me to long away to get the right answer ;(

As this level stands now (and after working on it at length), one or two of these clues should be built into the puzzle (sourcecode, etc). The hint at the solution is three-ways ambiguous, without sufficient evidence to lead one down the correct path.

First: It turns out that the sequence provided can lead to separate sequence corresponding to the young-fibonacci lattice (no, this isn't a spoiler, or the answer), indexed by the fibonacci sequence. A rather startling, and ultimately frustrating, coincidence, I must say.

The second is detailed earlier in this thread (incorrect or not)

And the third leads to the correct answer.

I sure learned quite a bit, though. It's a bummer having to resort to the hint forum for clues that could be, instead, more cleverly embedded in the level.

Hello,

I think I found the answer.

But when I take the 30 number of the len of that number I get a 404 page.

So len(a[30]) is not the lenght of the 30 number ??

Roelof

P.S.

One thing I dont get.

if you have 1121 I thought the answer would be 211211 but it is 111221

Very wierd.

Im stuck
