Constructablility is vague, so how am I supposed to know which context? Anyway, as I said, constructablility is not integral to blockicness. Constructibility is directly relevant to Blockicness, though -- Blockic constellations appear in contexts where constructibility matters. The advantage of res...

Do you understand the difference between slow salvo construction and an arbitrary glider synthesis?

Anyways, you only need 2 gliders for a bi-block - same as a block.

This topic is covered in chapter 5.7 "Slow salvo synthesis" in the textbook.

I prefer option 1 (leave the current name). I would agree with option 2 (use the rulestring) if there was a good chance that this will settle the issue and the article title will remain a rulestring.

This has the c/6d ship found in lenia and other rules, and no other known ship as of right now Isn't Lenia a completely different kind of CA ?

The fact that "condition" has been used does not mean that its use is common .

If you do want to talk about a static instance of a CA pattern, condition might be the right word - but I feel that that is not what is done. Conditions are actually static (unless one uses an alternating rule , or otherwise changes the rule over time). For example if the B6 condition (birth on 6 a...

Two engine Cordership:

I think this is a corderoid spaceship. A Cordership would necessarily have simplified speed c/12d and would be based on switch engines.
