comment partial sums of fractional parts
Isn't $S(28,18,1/2) = 336/23$, considerably larger than your numerics suggest?

comment partial sums of fractional parts
Just to be clear, typically $S(p,q,\alpha)$ is negative, and can be arbitrarily negative, you just want to bound how positive it can become?

comment Expected symmetry in the diophantine approximations of an irrational number
Do you have a proof that there are no upper ones? I think defining $x$ through its continued fraction may be more tractable, say $x=[0;10,1,100,1,1000,1,\dots]$.

comment Most interesting mathematics mistake?
That's what I had in mind, sorry for the confusion. But in my defense, can't circles on the surface of a torus have 4 intersections? And $p$-adic circles have infinitely many?

comment How to efficiently sample uniformly from the set of p-partitions of an n-set?
If $N=a_1+\dots + a_k$ is a random integer partition, and $x_1,x_2,\dots,x_N$ is a random permutation, then $\{ \{ x_1,\dots,x_{a_1}\}, \{x_{a_1+1},\dots,x_{a_1+a_2} \}, \dots \}$ is a random set partition. It isn't clear to me that it won't be uniformly random.

comment From reducible polynomial to an irreducible one
This is a ring (just not one with unity). In any case, the OP asked for "an algebraic construction".
