re: More than 3000, less than 8, computer solutions | Comment 2 of 4 |
(In reply to More than 3000, less than 8, computer solutions by Charlie)

Hi, Ch

When I created this puzzle, it was done "bottoms up" i.e. describing a certain number by its features,- without checking for redundant solutions.

 Since I have anticipated multiple solutions (I assumed 5-10 distinct possibilities, not 3000) I have added that "the digits of  base 16 representation form an arithmetic progression".

This amendment (somehow run away ?) should make (hopefully)the puzzle uniquely solvable.....likely, not sure...

Since the solution I had in mind was not mentioned by   you, I

would ask, time permitting, that you add the above constraint to your program and by doing this you will significantly improve my puzzle-


Better late tan never.
