I was interested in this problem in GCJ Finals and thought of its general case (= the board size is infinite).

Rule

You are given two (or more) type of polyominoes. Find a shape satisfies the condition "can be filled completely with some number of polyominoes of the same type in no overlaps" for each type of polyomino.

A shape with fewer cells is considered better but it's not necessary to minimize.

The thing you are referring to is called "least common multiple of polyominoes", some known results in this field are google-able.

    Thanks! That's a keyword exactly I wanted to know. However I googled and got no result for exact phrase and few results for polyominoes or LCM. Was my use of google something wrong?
