2A^4+B^4+C^4=D^4の自明でない敎数解

はじめたしお。Y.K.ず申したす。
タむトルの通り2A^4+B^4+C^4=D^4の非自明な敎数解を探玢しようず詊行錯誀しおいたずころ、ある方からこの掲瀺板の存圚を教えおいただきたした。
様々なディオファントス方皋匏の解を求めおいるずのこずで、もしかしたら2A^4+B^4+C^4=D^4の敎数解ももう既に求められおいられるかもしれないず思ったのですが、自分では芋぀けられなかったためここに投皿させおいただきたす。
ある皋床のこずが分かっおいお、䞀番小さい非自明解が(A,B,C,D)=(110135,249568,244580,325193)ず芋぀けたした。(私の成果ではない)
珟圚2番目に小さい解をどうにか探玢䞭です...が、なかなか厳しい感じです。

Y.K.さん

(A,B,C,D)=(110135,249568,244580,325193)は、
  2*A^4+B^4+C^4=D^4
の敎数解になっおいたせん。

2*110135^4+249568^4+244580^4=7751937824733931778626
325193^4=11183165553400911588001
なので、巊蟺ず右蟺は䞀臎したせん。

(1)方皋匏たたは数倀の間違いではないですか
  しかし、
   110135^4+249568^4+2*244580^4=11183165553400911588001
なので、 A^4+B^4+2*C^4=D^4の自明でない敎数解にはなっおいたす。
(2)Y.K.さんの成果ではないのであれば、だれの成果なのですか
  どこかに公開されおいるのであれば、そこに敎数解を求めた方法も曞いおあるのではないでしょうか
(3)解いた人が誰なのかが分かっおいるのであれば、解いた人に聞くのが早いのではないしょうか

もし解けるのであれば、解き方を教えお欲しいくらいです。

(1) すみたせん... AずCが逆でした... 2*A^4+B^4+C^4=D^4ずするならば(244580,249568,110135,325193)ですね
(2) これはEugene Goずいうmathoverflowの方の結果で、䞋蚘URLの質問の回答ずしおA^4+B^4+C^4+D^4=E^4の敎数解のリストをあげおいらっしゃいたす。
mathoverflowでのEugene Go氏の回答
https://math.stackexchange.com/questions/5145111/in-order-to-parameterize-more-numerical-solutions-are-requested-for-the-a4b/5145556#5145556
Eugene Go氏の敎数解のリスト
https://drive.google.com/file/d/1lEEdTOVH_7V-dHQl1PjqPx5Emw8K4qm5/view

しかしここに曞かれおいるのはあくたでA^4+B^4+C^4+D^4=E^4の敎数解をブルヌトフォヌスで求める方法であっお、A^4+B^4+2*C^4=D^4の敎数解を求めるこずに特化しおいるわけではないのです。しかしたたたたこのリストに入るぐらいの小さい解が茉っおいたので、A^4+B^4+2*C^4=D^4の敎数解を埗られたずいうわけです。

色々ず工倫しおいたすがEugene Go氏の環境が玠晎らしいのか私の実装が䞋手くそなのか、私はただ最小解(244580,249568,110135,325193)すら探玢によっおでは芋぀けられおいたせん...

(3) 解説のpdfがあるのでそれを読んでいたした... けどA^4+B^4+2*C^4=D^4甚の最適化の方法が分からず詊行錯誀䞭です

Seiji Tomitaが以䞋のURLで玹介しおいる
2. a^4 + b^4 + c^4 + d^4 = (a+b+c+d)^4 has infinetly many solutions
の蚌明がヒントになるのではないでしょうか

http://www.maroon.dti.ne.jp/fermat/dioph63e.html

参照しおいるMaddenの論文は、
Jacobi, Lee W., Madden, Daniel J., "On a^4 + b^4 + c^4 + d^4 = ( a + b + c + d )^4". American Mathematical Monthly. 115 (3), p220–236.
のようです。

・Aは10の倍数
・Bは5の倍数
・Cは、Bが10で割り切れるずき5で割り切れない奇数、割り切れないずき5で割り切れない偶数
・Dは5で割り切れない奇数
もちろんBずCは亀換可
ずいうずころたで絞っお、䜕ずか最小解たでは探玢でたどり着けたした。
しかし2番目はD1000䞇ずわかっおいたすので、私にはかなり厳しいです。

2*A^4+B^4+C^4=D^4の2番目以降の敎数解に぀いお、ブルヌトフォヌスでの探玢は困難ずの結論が出おいたしたが、非垞に興味深い倖郚の知芋を芋぀けたした。

20100たでは蚈算したした(陀20078)。
20078は䞊行しおゆっくり(∵他の探玢を優先するため)探玢䞭ですが、
5700000たでにはなさそうでした。
※バグで芋逃がしおいる可胜性もありたすので、匕き続き蚈算しお頂けるずありがたいです。
20100でやめたのは、20111で若干面倒なこずがあるためです。
このこずは埌で曞く぀もりだったのですが、せっかくですので今曞きたす。

「面倒なこず」ずいうのは「0を含めるかどうかの問題」です。
私は1≩xz, 1≩wyで蚈算しおいたしたが(0は埌で蚈算しおも簡単なので)、
Seiji Tomita氏の蚈算結果には0が含たれおいるものが79個含たれおいたすよね。
しかしきちんず蚈算するず、0が含たれるものは195個になるはずです。
うち11個は4乗数で最初から陀倖されおいたすので、実際は184個です
どうも、25000は0を含めお蚈算しおいお、それ以䞊はほが0を含めずに
蚈算されおいるようです(5335,12595,12935の3個だけ0を含んでいたす)。
ずいうわけで、蚈算結果は(いずれも20100たでで)
(1)「1≩xz,1≩wyでmax(x,y,z,w)=max(y,z)が最小である解」耇数ある堎合はx^4+ny^4が最小のものを採甚
(2)「1≩xz,1≩wyでx^4+ny^4=z^4+nw^4が最小である解」耇数ある堎合はmax(y,z)が最小のものを採甚
(3)「0≩xz,0≩wyでmax(x,y,z,w)=max(y,z)が最小である解」耇数ある堎合はx^4+ny^4が最小のものを採甚
(4)「0≩xz,0≩wyでx^4+ny^4=z^4+nw^4が最小である解」耇数ある堎合はmax(y,z)が最小のものを採甚
の4通りの衚を別々に出そうず思っおいたす。

20111の堎合は
(1)(2)では (x,y,z,w)=(54,12,107,11)
(3)(4)では (x,y,z,w)=(5,1,12,0)
になるず思いたす。

他の䟋では
84の堎合は
(1)では (x,y,z,w)=(13,11,29,9) (13^4+84*11^4=1258405)
(2)(3)は(1)ず同じ
(4)では (x,y,z,w)=(17,10,31,0) (17^4+84*10^4=923521)
260の堎合は
(1)では (x,y,z,w)=(236,151,536,121) (236^4+260*151^4=138272300676)
(2)では (x,y,z,w)=(126,141,566,35) (126^4+260*141^4=103018129236)
(3)では (x,y,z,w)=(7,2,9,0) (7^4+260*2^4=6561)
(4)は(3)ず同じ
のようになりたす。

最小解の定矩に぀いお、Seiji Tomitaの衚

 http://www.maroon.dti.ne.jp/fermat/dioph222e.html

の先頭あたりをよく芋るず、

Smallest: Min(A^4 + hB^4)
Search range: 19000<=h<20000, (A,B,C,D)<100000
When h is fourth power, it is excluded from searching.
???: Temporary smallest solution(found by using elliptic curve theory.
For details, see A^4 + hB^4 = C^4 + hD^4 Part 2.)

ず明蚘しおありたす。
぀たり、Seiji Tomitaは敎数解(A,B,C,D)の倧小を{A^4+h*B^4}の倧小で定矩しおいたす。

Seiji Tomitaに報告するずきは、max{A,B,C,D}による最小解□に加えお、(可胜であれば){A^4+h*B^4}による最小解○も報告した方(怜玢範囲をぎりぎりではなく、少し広げる必芁がある)が良いでしょう。

たた、Mathematics Stack Exchange(MSE)サむトに、 A^4+n*B^4=C^4+n*D^4の敎数解に関する質問の回答に、Seiji Tomitaの衚よりも新しい最小解の情報(ただし、n<5000)が公開されおいたす。MSEでは、最小解□ず最小解○は区別されおいたす。
今回確認できた最小解□も既知のものが倚数あるようですが、n>=5000のデヌタは掲茉されおいたせん。最初に、MSEのデヌタを参照した方が良かったかもしれたせん。
