 <p><strong>Range</strong> (<code><span class='Function'>↕</span></code>) is extended to apply to a list of natural numbers, in addition to the provided case of a single natural number (an enclosed natural number <code><span class='Value'>𝕩</span></code> should still result in an error). For a list <code><span class='Value'>𝕩</span></code>, the result is an array of shape <code><span class='Value'>𝕩</span></code> in which the value at a given index is that index, as a list of natural numbers. That is, <code><span class='Value'>i</span><span class='Function'>≡</span><span class='Value'>i</span><span class='Function'>⊑↕</span><span class='Value'>𝕩</span></code> for any list of natural numbers <code><span class='Value'>i</span></code> with <code><span class='Function'>∧</span><span class='Modifier'>´</span><span class='Value'>i</span><span class='Function'>&lt;</span><span class='Value'>𝕩</span></code>.</p>
 <h3 id="searching">Searching</h3>
 <p><strong>Match</strong> (<code><span class='Function'>≡</span></code>) indicates whether two values are considered equivalent. It always returns 0 or 1, and never causes an error. If both arguments are atoms then it is identical to <code><span class='Function'>=</span></code>, and if one is an atom and the other an array then it returns 0. If both arguments are arrays then it returns 1 only if they have the same shape and all pairs of corresponding elements match. Fill elements aren't taken into account, so that arrays that match might still differ in behavior. <strong>Not Match</strong> simply returns the complement of Match, <code><span class='Function'>¬≡</span></code>.</p>
-<p>Monadic search functions compare the major cells of <code><span class='Value'>𝕩</span></code> to each other. <code><span class='Value'>𝕩</span></code> must have rank at least 1. Except for Unique (<code><span class='Function'>⍷</span></code>), the result is a list of numbers with the same length as <code><span class='Value'>𝕩</span></code>.</p>
