FORMULA
| a(n) = n for n > 5
|
|
|
EXAMPLE
| For n>1, a(2n) = 2n because a square can be dissected into a square with edge (n-1)/n times the original square and a strip of n and a strip of n-1 squares (each with edge 1/n times the original square). For n>1, a(2n+3)= 2n+3 because one square in the above example can be dissected into four equally sized squares.
