An integer
is
-balanced
for
a prime if, among all nonzero binomial coefficients
for
, ...,
(mod
), there are equal numbers of quadratic residues and nonresidues
(mod
).
Let
be the set of integers
,
, that are
-balanced. Among all the primes
, only those with
, 3, and 11 have
.
The following table gives the -balanced integers for small primes
(OEIS A093755).
