</table>Selingerhttps://www.hexwiki.net/index.php?title=Edge_template_VI1b&diff=8309&oldid=prevSelinger: Added a page for a new 6th row template with 1 stone2023-10-07T01:13:19Z<p>Added a page for a new 6th row template with 1 stone</p>
<p><b>New page</b></p><div>Template VI1-b is a 6th row [[edge template]] with one stone.<br />
<br />
<hexboard size="6x19"<br />

<br />
The template was discovered by Eric Demer, in answer to an open question about 7th row ladders from the page [[Open problems about edge templates]]. Unlike [[edge template VI1a]], there is no empty cell required to the left of the template's stone. <br />
<br />
The template's validity and minimality have been verified using [[MoHex]].<br />
<br />
== Overview of how the template works ==<br />
<br />
There are many individual intrusions to consider, but the following information offers a birds-eye view on how the template works.<br />
For all intrusions ''except'' at the cell marked "*", the shaded area is sufficient for Red to reconnect:<br />
<br />
<hexboard size="6x19"<br />
coords="none"<br />
edges="bottom"<br />
visible="area(a6,s6,s4,q2,m1,i1,c4)"<br />
contents="R i1 E *:h3 S area(a6,o6,o4,m2,k1,i1,c4)"<br />
/><br />
<br />
If, on the other hand, Blue intrudes at "*", then Red can bridge to the right and connect by [[edge template V1b]].<br />
<br />
<hexboard size="6x19"<br />
coords="none"<br />
edges="bottom"<br />
visible="area(a6,s6,s4,q2,m1,i1,c4)"<br />
contents="R i1 B 1:h3 R 2:j2 S area(k1,f6,s6,s4,q2,m1)"<br />
