  We consider an infinite family of exponents $e(l,k)$ with two parameters, $l$
and $k$, and derive sufficient conditions for $e(l,k)$ to be 0-APN over
$\mathbb{F}_{2^n}$. These conditions allow us to generate, for each choice of
$l$ and $k$, an infinite list of dimensions $n$ where $x^{e(l,k)}$ is 0-APN
much more efficiently than in general. We observe that the Gold and Inverse
exponents, as well as the inverses of the Gold exponents can be expressed in
the form $e(l,k)$ for suitable $l$ and $k$. We characterize all cases in which
$e(l,k)$ can be cyclotomic equivalent to a representative from the Gold,
Kasami, Welch, Niho, and Inverse families of exponents. We characterize when
$e(l,k)$ can lie in the same cyclotomic coset as the Dobbertin exponent
(without considering inverses) and provide computational data showing that the
Dobbertin inverse is never equivalent to $e(l,k)$. We computationally test the
APN-ness of $e(l,k)$ for small values of $l$ and $k$ over $\mathbb{F}_{2^n}$
for $n \le 100$, and sketch the limits to which such tests can be performed
using currently available technology. We conclude that there are no APN
monomials among the tested functions, outside of known classes.
