comment A function which determines whether a function is odd, even or none, functional?
@gniourf_gniourf I have a follow up question, how does this work with self-referencing functions? E.g. if I call the functional above $E$, a function $T$ maps (0, -1, 1) to (0, 0, 1), then where does this go wrong? $f(x) = x^{T(E(f))}$

comment Finding solution to matrix equation over GF(2) with minimal true variables
This question is equivalent to this question on theoretical computer science. It is NP-complete through a reduction to the minimal-weight code problem.

comment Dividing an angle into $n$ equal parts
My answer was incorrect (and trivially so - it implied you can trisect an angle). Oops.

comment Example of uncomputable but definable number
Could you elaborate what qualifies as a 'really really simple' for the algorithm of $f$?
