p=11ね
下記のGaloisは、Chevalierへの手紙で
楕円曲線の等分問題で、p = 11の解法を取り上げている
英文によるfulltextを探すと、下記がヒットしたので貼る

彼は、20歳で亡くなったという
存命ならば、ここらは論文として出版されたろうに
なお、GaloisのChevalierへの手紙については
下記高木先生の近世数学史談でも、これは取り上げられている

The Last Mathematical Testament of Galois
Evariste Galois's last mathematical testament in the form ofa letter to his friend Auguste Chevallier is
reproduced here in English translation I.

P3
The last application of the theory of equations is related to the modular equation of elliptic functions.

P5
For p = 7 we find a group of (p + 1) (p - 1) /2 permutations, where
∞ 1 2 4
are respectively related to
0 3 6 5.
This group has its substitutions of the form
略
b being the letter corresponding to c, and a a letter which is a residue or non-residue
according as c.

For p = 11, the same substitutions take place with the same notations,
∞ 1 3 4 5 9
are respectively related to
o 2 6 8 10 7.
Thus, for the case of p = 5,7,11, the modular equation is reduced to degree p.
In all rigor, this reduction is not possible in the higher cases.

The third paper concerns the integrals.
We know that a. sum of terms of the same elliptic function is always reduced to a
single term plus algebraic or logarithmic quantities.
