■Diophantine Equation
       A^4+B^4+n^2*C^4=D^4 ----------(1)
を満たす自明でない整数の組(A,B,C,D) (ただし A*B*C*D!=0かつgcd(A,B,C,D)=1)を探す。

以下では、Elkiesの論文(参考文献[1])の方法によって、(1)を満たす整数の組(A,B,C,D)を探す。

■(1)およびD!=0より、r=A/D,s=B/D.t=C/Dとすると、
       r^4+s^4+n^2*t^4=1 ----------(2)
つまり、(2)を満たす有理数の組(r,s,t)を見つければ良い。

(3)で、r=x+y,s=x-yとすると、
       2*(x^4+6*x^2*y^2+y^4)+n^2*t^4=1 ----------(3)
となる。

ここで、ある有理数uに対して、
       r=x+y, s=x-y ----------(4)
       ±(u^2+2)*y^2=-(3*u^2-8*u+6)*x^2-2*(u^2-2)*x-2*u ----------(5a±)
       ±n*(u^2+2)*t^2=4*(u^2-2)*x^2+8*u*x+(2-u^2) ----------(5b±)
を満たす有理数の組(x,y,t,r,s)が存在すれば、(r,s,t)が(2)を満たすことが分かる。

■２次曲線(5a±),(5b±)は、常にnon-singularある。
２次曲線(5a±)の右辺の判別式は
4*(u^2-2)^2-4*3*u^2-8*u+6)*(2*u)=4*(u^2-4*u+2)*(u^2-2*u+2)
となり、有理数の根を持たないので、任意の有理数uについて、non-singularである。

同様に、２次曲線(5b±)の右辺の判別式は
(8*u)^2-4*4*(u^2-2)*(2-u-2)=16*u^4+64=16*(u^2-2*u+2)*(u^2+2*u+1)
となり、有理数の根を持たないので、任意の有理数uについて、non-singularである。

■方程式系(4),(5a±),(5b±)は、involution τ:(u,x,y,t)→(2/u,-x,y,-t)で不変であることが分かる。

τ:(u,x,t)→(2/u.-x,-t)の変換で方程式系(5a±),(5b±)の有理数解(x,y,t)の集合は不変であるので、uの分子は0でない偶数,uの分母は正の奇数として良い。

■有理数uの高さが小さいものから、順に調べる。
例えば、有理数uの高さが200以下の範囲で、uの分子が偶数、uの分母が奇数であり、２つの２次曲線(5a+)と(5b±)が共に有理点を持つようなuを選択すると、以下のように1448個のuが抽出される。

■これらのuについて、(3),(5a),(5b)を満たす有理数解(x,y,t)を持たないものもあれば、有理数解(x,y,t)を持つものもある。
これらのuを順に調べれば良い。

ここからは、A^4+B^4+100*C^4=D^4(n=10のとき)と同様なので、最終的に得られた整点のみ記述する。
ここで、対応する整点が見つかった各有理数uについて、0 lt:= A <= B, 0 < C, 0 <: Cを満たすように、A,B,C,Cの符号を変更したり、A,Bを交換して、Dの小さい順に並び替えると、以下のようになる。

u=-200/159のとき
