1,11,21,1211,3112,132112... what will be the next number. Answer with justification

Why do you want us tod find the next number and do it with justification. Just curious.

Ms tickle

You have to think outside the box for this one.

It's a slightly altered version of a quite famous sequence.

The next numberseems to be 311322,

Can you work out why?

Who, me or samss40 ?

And after that comes 232122. Strange how the sequence decreases at that point, eh?
