<p>Many implications among properties of loops are built directly into <strong class="pkg">LOOPS</strong>. A sizeable portion of these properties are of trivial character or are based on definitions (e.g., alternative loops <span class="SimpleMath">\(=\)</span> left alternative loops <span class="SimpleMath">\(+\)</span> right alternative loops). The remaining implications are theorems.</p>

<p>All filters of <strong class="pkg">LOOPS</strong> are summarized below, using the <strong class="pkg">GAP</strong> convention that the property on the left is implied by the property (properties) on the right. <br /> <br /> <code class="code">( IsExtraLoop, IsAssociative and IsLoop )</code> <br /> <code class="code">( IsExtraLoop, IsCodeLoop )</code> <br /> <code class="code">( IsCCLoop,
