Those are amazing! Hard to believe how many variants of the Delta (and Atlas) there were! Surprising to think that the Titan sheet may well have the fewest number of variants on it.
I'll have too see once I will begin fix the existing sheet and add the few variants still missing. But yes, it is highly possible that the Titan sheet could be the smallest of the three.

Oh man, I love the crazy Delta IV derivatives. For those unaware, the 7-CBC superheavy could rival Saturn V in LEO throw weight. I'm not familiar with this specific generation of next-gen Delta, but I wouldn't be surprised if it could surpass S-V.
(PDF from ULA on Delta IV derivatives
ULA's payload guide for the Delta IV has a small section at the end with some possible evolutions (since it dates 2013, and ULA is now working on the Vulcan to replace both Atlas and Delta, I'd say they pretty much will never happen). They claim the 8-m CBC next-gen could lift 145T to LEO.
