 <p>BQN replaces the <a href="https://aplwiki.com/wiki/Key">Key</a> operator from J or Dyalog APL, and <a href="https://aplwiki.com/wiki/Partition_representations">many forms of partitioning</a>, with a single (ambivalent) Group function <code><span class='Function'>⊔</span></code>. This function is somewhat related to the K function <code><span class='Function'>=</span></code> of the same name, but results in an array rather than a dictionary.</p>

 <h2 id="definition">Definition</h2>
 <p>Group operates on a list of atomic-number <a href="indices.html">indices</a> <code><span class='Value'>𝕨</span></code> and an array <code><span class='Value'>𝕩</span></code>, treated as a list of its major cells, to produce a list of groups, each containing some of the cells from <code><span class='Value'>𝕩</span></code>. The two arguments have the same length, and each cell in <code><span class='Value'>𝕩</span></code> is paired with the index in <code><span class='Value'>𝕨</span></code> at the same position, which indicates which result group should include that cell.</p>
