Recursive islands and lakes

From Wikipedia, the free encyclopedia

A recursive island or lake is an island or a lake that lies within an island or a lake.[1] For the purposes of defining recursion, small continental land masses such as Madagascar and New Zealand count as islands, while large continental land masses do not.
