Exercise 44. [M04] [M04] Could the clues of a sudoku puzzle be the first 33 digits of $\pi$? (See (29a).)
Verified: yes
Solve time: 3m22s
The first $33$ digits of $\pi$ are
$$ 3,1,4,1,5,9,2,6,5,3,5,8,9,7,9,3,2,3,8,4,6,2,6,4,3,3,8,3,2,7,9,5,0. $$
A sudoku clue must be a digit from $1$ through $9$, because each cell value represents one of the nine possible symbols. The $33$rd digit in this sequence is $0$, which is not an allowable sudoku value. Therefore the clues in (29a) cannot be the first $33$ digits of $\pi$.
$$ \boxed{\text{No}} $$
