Legii

Today I have been sorting bricks - mainly to transfer them from 17 different sizes of unstackable boxes to one size of stackable box, in some sort of logical fashion.

There are too many logical fashions.  The ideal sorting solution requires 400 billion* separate boxes.

*"More than 400 billion Lego bricks** have been produced since 1958. There are about 62 Lego bricks per person of the Earth's population." according to some random page found on the interweb.

** Most of them seem to be our basement.
