113313211

1113213211.

Each number describes the number before it (1-1, 1-3, 2-1, etc.).

...but remember, I don't know much... I'm just a dumb bunny....



(P.S. Do I win a... SOPHIE? *thumpthumpthump*)

Fuzzy knows much!!

I thought I would elaborate by what you mean as "describes":

Each string beginning with the second is a 'description' of the preceding string. The second string, '11', describes the first: it contains one 1. The third string, '21', describes the second: it contains two 1's. The sixth string, '312211', describes the fifth: it contains three 1's followed by two 2's followed by one 1.

Thanks, and thanks Zatarra... very kind of you...

...but let's be very clear here: I'm NOT sharing my SOPHIE. Mine mine mine! *thumpthumpthump*
