Thank you for the encouragement on my D5 Coalition research, hoosiermama. I suspect there really are connections there we have not seen yet. I do have some other data to post.
The other solutions offered for the D5 reference are also plausible and need to be considered along with this one.
We are a brain storming group, and IMHO, we should not be about limiting ourselves, or the work of contributors.
Not only theD5 Coalition but also the other solutions - avalanche, the construction equipment, the chess square/move, the Trident II D5, and the D5 Nations, cited by Aquamarine - should all be considered until more data is forthcoming.
But that’s just me.
I concur No one should manipulate or shut down conversation.
This should be an open brainstorming thread not controlled by a few. All should be welcomed and encouraged. Only thing not allowed is personal attacks and swearing.
