  Definition: Mekso unary or binary operator: $n$-set or integer interval; in
       unary form, it maps a nonnegative integer $X_1 = n$ to the set
       $\1, \dots , n\$ (fully, officially, and precisely: the
       intersection of (a) the set of exactly all positive integers
       with (b) the closed ordered interval [$1, n$] such that $n \geq
       1$; see notes for other $n$); in binary form, it maps ordered
       inputs $(X_1, X_2) = (m, n)$ to the intersection of (a) the set
       of exactly all integers with (b) the closed ordered interval
       [$m, n$].
       Notes: $0$ on its own induces the unary form of this word and thus
       maps to the empty set ∅. Inputting infinity (for the unary
       form) produces the set of exactly all positive integers
       (sometimes also onown as: natural numbers), $Z^+ = N$. The
       upper bound is always specified; when the lower bound is not
       specified, it defaults to $1$ and the upper bound must equal or
       exceed $1$ (else the output is ∅). If this word is represented
       by $f$, and $Z$ represents the set of exactly all integers, and
       $(n, m \in Z \cup$ Set$(\pm \infty$)$: m \leq n)$, then: $f(m,
       n) = Z \cap [m, n]$, and furthermore: if $1 \leq n$, then $f(n)
       = f(1, n) = Z \cap [1, n]$, else $f(n) =$ ∅. The definition
       extends naturally (and with only trivial modification) to
       non-integer real-valued $n, m$, but it is recommended to keep
       them as integers when possible. $Z$ excludes $\pm \infty$.
