comment Flaw or not flaw in Excel's RNG?
Actually, because of the $\mod 1$, there is a term missing: $$mx=(qr)ix+(pr)iy+(pq)iz-mn$$ with some integer $n$. However, that does not change the answer, since, for example modulo $p$, $mn$ is zero. Good point also about the numerical precision, I'll have a look tomorrow (I don't have Excel 2003 or 2007 at home, and I read somewhere that they switched to Mersenne Twister now).

@Winther How could I possibly miss this? I saw the first equation, but completely failed to see the common $p$ factor, hence the simplification when taking $\mod p$. Thank you! Make this an answer, you deserve the bounty, and I deserve a good kick in the sas!

comment Question about Chebyshev Polynomials in Beardon
If $(T_k)^n$ means composition: $T_k\circ T_k\circ\dots\circ T_k$, then it's ok, since, for example, $T_k(T_k(\cos x))=T_k(\cos kx)=\cos k^2x$, and more generally, $T_p\circ T_q=T_{pq}$.

comment What are some theorems that currently only have computer-assisted proofs?
Not a computer-only proof, since it's a formalization of a proof by Gödel. I don't think it qualifies as mathematics either. Ontology rather belongs to metaphysics.
