Note that these are combinational circuits, not sequential - so no feedback or clock are required. &lt;a href=&quot;https:&amp;#x2F;&amp;#x2F;www.nayuki.io&amp;#x2F;page&amp;#x2F;aes-cipher-internals-in-excel&quot; rel=&quot;nofollow&quot;&gt;https:&amp;#x2F;&amp;#x2F;www.nayuki.io&amp;#x2F;page&amp;#x2F;aes-cipher-internals-in-excel&lt;/a&gt; , &lt;a href=&quot;https:&amp;#x2F;&amp;#x2F;www.nayuki.io&amp;#x2F;page&amp;#x2F;des-cipher-internals-in-excel&quot; rel=&quot;nofollow&quot;&gt;https:&amp;#x2F;&amp;#x2F;www.nayuki.io&amp;#x2F;page&amp;#x2F;des-cipher-internals-in-excel&lt;/a&gt;</text></comment>

It is a great example of the thing I’m talking about. Realized after the fact that I failed to plant my context in my comment, before doing my graybeard routine.&lt;p&gt;So. Food for thought, our LLM overlords are just unfathomable spreadsheets.</text></comment>
