Oct 30, 2023 at 13:01 comment added David @Daniel Loughran. Thanks for answering the question. I know my question has been up for some ten long days. I've put up a bounty so hopefully if there are more answer's I will get an option to select one. Right now, yours is the only single answer. Also, I appreciate the time & effort others have put into giving their comments.

Oct 26, 2023 at 15:42 comment added David @Daniel Longhran, Portion of your previous comment is pasted here [ "To add to Silverman's remark: In the case, (x1)^d+(x2)^d=(x3)^d+(x4)^d, with d≥5, depending on one's viewpoint a "formal for a general solution" should indeed exist" ]. So what is view on exponent (d=4). With hindsight from the comments of Naom Elkies & Joe Silverman I think viewers would appreciate if they see a (part two) of your answer.

Oct 19, 2023 at 18:06 comment added sdr This degree 4 equation defines a K3 surface, which is not unirational (in contrast to the degree 3 case, where it is unirational). Basically by definition of "unirational," this means there's not a nice formula for the general solution of the type you are probably imagining.
