The following problem is open in the sense that no solution is currently known. Progress on the problem may be awarded points. An example of progress on the problem is a non-trivial bound on the sequence deﬁned below.
For each integer

n\ge2

, consider a regular polygon with

2n

sides, all of length

1

. Let

C(n)

denote the number of ways to tile this polygon using quadrilaterals whose sides all have length

1

. Determine the limit inferior and the limit superior of the sequence deﬁned by

\frac1{n^2}\log_2C(n).
