Final proposition of Fermat

Pierre de Fermat, genius mathmatician in 19 century, written various proofs on his favorite book's blank. There is a below numerical formula. A^n+B^n=C^n {A, B, C and n are nutural number} More than 3, the number of n which satisfy that formula is not exist. Moreover, there is such comment. I found amazeing perfect proof of this formula, but this blank is too narrow to write this proof. Since this comment, 400 years no one could not find this formula's proof. But in 1994 this formula had proven. There is big effect by Japanese mathmatician. Toyo Taniyama and Goro Shimura. I know their everything, but this brog capacity is too small to write their everything.
