I am trying to figure out how to implement a Monte Carlo method for solving sudoku. I am looking at this blog post, however I can not figure out at all where he is pulling the number 243 out of

Where 243 is the minimal energy of the system.
I got it right as i posted the question.
9 unique elements in each row, * 9 rows = 81 9 uniqe elements in each col, * 9 col = 81 9 unique elements in each box * 9 boxes = 81
81 * 3 = 243
