Verification Calculations for Trivia Propositions

Manage Bookmarks
This is a verification calculation within a limited scope for Trivia Proposition No. 30, inspired by Fermat’s Last Theorem.
\(\normalsize \hspace{10px} {\large \displaystyle \sum_{\small j=0}^{\small n-1}}(a+j)^n=b^n,\hspace{20px} n\ge 4 \\\)

There are no natural numbers a and b satisfying this equation for a natural number n≧4.
If b exists within the specified search range, the values of a and b are shown for each n.
If no b exists in that range, -- is shown for each n.
Initial values for n
~ Final value n≧2
Initial values for a
~ Final value a≧1
Note 1) Set the calculation precision to approximately n+1 times the maximum number of digits in a.
Note 2) An excessively large search range will time out.

Solutions to the equation above exist for n=2 and n=3.
 n=2,  32+42=52,  202+212=292,  ...
 n=3,  33+43+53=63

---Fermat’s Last Theorem ----------------
For an integer n greater than or equal to 3, Xn+Yn=Zn
there are no natural numbers X,Y,Z satisfying this equation
