if all of the prime powers in the factorizations of both x and y are

such that none of the p^a==-1 mod 4, then the substitutions you

suggest can be made, otherwise they cannot (in integers anyway)

So the first question (after giving up on the WTF!? question) is, how

are the x & y that cannot be integrally expressed as the sum of two

squares to be disposed.

The second question is how do we leap to Wiles-FLT when our x & y have

differing exponents with severe constraints (base equals exponent of

the other and vice versa)?

If you sense it doesn't make sense (you are quite correct in my case

by the way), you should be able to anticipate the most likely

questions, thus you could start answering and clarifying those without

need of further input.

Are you saying Mark's findings ultimately represent proof of FLT,

Goldbach, twin prime conjecture and primes between squares?

Curiously yours,
