I meant the number of sudoku puzzles with exactly one solution.
Probably the question I just posted is not correct.So here is my next puzzle:
This is an extract from J.A.H. Hunter's excellent puzzle book,"Challenging Mathematical Teasers":
Mike put down his ruler. "That's it.Look at the triangles I've drawn,Dad," he said. "Each area is exactly 2/3 rds its perimeter."
"You mean in square inches and inches?" Victor looked. "One of them seems kind of thin."
"Sure, but it is a triangle.All the sides of these triangles are whole numbers of inches."
What were the dimensions of Mike's triangles?
sudoku puzzle, great blog man.
