in Further Arithmetic Integers
K Sengupta asked for integer solutions
to x^4+y^4=z^4-64 with z>y>x>0 and in arithmetic sequence

My question is concerning the more general problem
x^4+y^4=z^4-n with z>y>x>0 and in arithmetic sequence

and for what values of n are there only two solutions

(In reply to Comments On Part Two by K Sengupta)

My previous version of "Comments On Part Two" was inaccurate and stemmed from a misunderstanding of the tenets  corresponding to the problem.
I confirm having obviated the anomalies inclusive of the said version.
