[FOM] 789: Revolutionary Possibilities/8

The two proposed purely number theoretic statements in section 3 of
https://cs.nyu.edu/pipermail/fom/2018-February/020836.html need to be
strengthened, as they are trivially provable as they are written. They
are

THEOREM 3.1. For all k,n, some >=k element factor set has at most
ceiling(log(k))+1 quadratic residues mod n.

THEOREM 3.2. For all k,n, some >=k element factor set has at most
ceiling(log(k))+1 quadratic residues mod the first prime after
min(S\{1}) and k.

We propose the following fixes.

DEFINITION. The upper quadratic residue of positive integer t is t^2
modulo the least prime > t.

THEOREM 3.1. For all k,n, some >=k element factor set has at most
ceiling(log(k))+1 upper quadratic residues <= n.

THEOREM 3.2. For all k,n, some >=k element factor set S has at most
ceiling(log(k))+1 upper quadratic residues <= min(S\{1})+n.
