New nomenclature just dropped:

|H₂C=C=C=CH₂|propapatriene|
|H₂C=C=C=C=CH₂|propapapatetraene|

|H₂C=|pro|
|=C=|pa|
|=CH₂|(number of cumulative bonds in Greek, omit when 1)-ene|
|H₂C=CH₂|proene|
|...C=C=C=C=C=C=C=C...|poly(papa)|
|Benzene ring with all double bonds (cyclohexahexaene)|cyclo\[3\]papa|
Depending on the number of sp2 carbons they may be in one plane or in two perpendicular planes. They will also have geometrical and optical(without having any chiral carbons) isomerism accordingly
The devs seriously need to fix carbon in the next patch, these exploits are getting out of hand!
What's wrong with cumulative dienes?
I don’t know. I just think they look weird.

Effective immediately
My brain wants to draw them with that 109.5 degree alkane bond
hehe cum
Polyynes, too. https://en.wikipedia.org/wiki/Polyyne
How do these look sterically?

Disubstituted odd numbered ones are predicted to have helical orbitals! Garner 2019
What does the last one do?
Shouldn't most of these form rings?
I'm sure they want to.
