Polynomial / in GF(2^8)?

> ring r=(2^8,z),(x,y),lp;

? not implemented
? error occurred in STDIN line 4: `a/b;`
Does this means I could not use / in GF(2^8),
will you implement that function in future?
Thank you very much!

Dear Xijin Tang,

the polynomial x-y is no unit in the ring GF(2^8)[x,y]. So Singular does not allow you to divide by it.

It would allow you to divide a by any number in the coefficient field, i.e. a polynomial only in z.

Sincerely,

Oliver Wienand
