Hi Steve, you can shorten your "X-Chain" as

SF(6C6B39)[r78c6=r2c6-r2c79=r1c8-r7c8=r8c9]-6r8c5

Hi Dan,

This is a morph of the May 18th puzzle.
Also May 19th was a morph of April 27th.
There could be others, recently.
I haven't checked.

Regards,
Blue.

Sorry about that Blue. I am a puzzle saver and have long strings of puzzles and many dups get morphed in the process. I will try to catch them.

Hi, Blue. How about the May 12 puzzle? I remarked at the time that it looked familiar, but I couldn't find which one it reminded me of.

It's interesting how we come up with different solutions. I liked my May 18 solution a lot more than what I came up with for this version.

Yes, it's a morph of the April 20th puzzle.

Steve,

Not all networks can be expressed as chains using (*) characters. That's possibly the case here.

You can replace the three initial terms with a single term:

Code: Select all

 (6): r78c6 = r2c6 - r2c79 = r1c8 - r7c8 = r8c9  =>  -6 r8c5

 - aka -

 finned mutant Swordfish c6b39\r28c8 w/fin cell r7c6  =>  -6 r8c5

Thanks, Danny. JC already pointed out that variant; lovely. However, if that alternative hadn't been available, is there a right way- preferably an elegant one- to do what I was trying to do?
