The starting point for this was two sets of b-blocks, those with 123 on the front in the middle of a quick six, and those with 456 on the front in the middle of a slow six, which allows a relatively large number of omits.</div><div><br></div><div>On Mon, 2025-12-22 at 11:12 +0000, Richard Pullin wrote:</div><blockquote type="cite" style="margin:0 0 0 .8ex; border-left:2px #729fcf solid;padding-left:1ex"><div>The first version I produced can be rung with just 2 singles, giving an exact 2-part with one single in each half (at the expense of an exact 4-part).
