3次等冪和兩層同側鏡反數組(可任意抹位)

2639495^k+5949362 ^k +3759284 ^k +4829573 ^k =3729584 ^k +4859273 ^k +2649395 ^k +5939462 ^k

K=1得17, 177,714

K=2得79, 818,833,617,054

K=3得394,742,028,494,706,892,124

將外層抹去,也是同側鏡反數組:63949 ^k +94936 ^k +75928 ^k +82957 ^k =72958 ^k +85927 ^k +64939 ^k +93946 ^k

說明:

(1)   等號的同側由兩層的鏡反數組成,如左1的2639495,左2的5949362,抹去外層得63949和94936,也是鏡反數.

(2)   可任意抹位,等式K=1,2,3,依然成立.
