(In reply to I suspect ... by Larry)

My programmatic error in not finding n= -2 as a solution was because I did not properly deal with floating point arithmetic error.

e.g. 64(1/3) = 4, but the computer representation for this was

3.9999999999999996

Once I corrected the program, it found the solution.
