Hi,
I have a question regarding substitute of an expression with index
variables..I need to make a table for some products of irreducible
polynomials (Irreducible factors of x^63 -1) . But they are so large and I
can't fit them into the columns of my table. So I need to use these
substitutions
{S_1, S_2, S_3, S_4, S_5, S_6, S_7, S_8, S_9, S_10, S_11, S_12, S_13, S_14}
: ------> {1 + x, 1 + x + x^2, 1 + x + x^3, 1 + x^2 + x^3, 1 + x + x^6,
1 + x^3 + x^6, 1 + x + x^2 + x^4 + x^6, 1 + x + x^3 + x^4 + x^6, 1 +
x^5 + x^6, 1 + x + x^2 + x^5 + x^6, 1 + x^2 + x^3 + x^5 + x^6, 1 + x + x^4
+ x^5 + x^6, 1 + x^2 + x^4 + x^5 + x^6}
***** The right side is a list of irreducible polynomials which is assigned
to {S_1, S_2,.... S_14}.*******
For example instead of putting this large expression (1 + x) (1 + x + x^2)
(1 + x + x^3) (1 + x + x^6) (1 + x^3 + x^6) (1 + x + x^2 + x^4 + x\^6) (1 +
x + x^3 + x^4 + x^6) (1 + x + x^2 + x^5 + x^6) in my table I can write it in
tems of S_i's in this form S_1 S_2 S_3 S_4 S_5 S_6 S_7 S_8.
I tried ReplaceAll but it changes i.e. the above example to S_1 (S_1+x^3)
(S_1+x_6) .... Which is not what I want.
Can anybody tell me how to do this.
Regards
CHEKAD
