Extension to #92462:
Each of the pyramids above has seven ‘degrees of freedom’ (i.e. you need seven numbers to uniquely describe it). Unfortunately, puzzles #9 and #10 only has six known numbers, so they are not uniquely solvable. In this light, I provide a puzzle which I believe IS uniquely solvable (albeit with negatives and/or decimals). The puzzle is:
_________11
_______?? ??
______31 ?? ??
____?? ?? ?? 44
___?? 52 ?? ?? ??
_61 ?? ?? ?? ?? ??
?? ?? ?? ?? 75 ?? 77
Disclaimer: I have not actually solved the puzzle. I probably will not post a solution either. Feel free to discuss as you wish!
