Minor Infinite Crisis #6 Geekery

Earth-247. Heh. I approve.

But is there a similar in-joke connecting John Byrne's Generations Earth to the number 154?

Any IDs for Earth-97 (Female versions of main heroes), Earth-898 (Western characters havinga Crisis at the Alamo) or Earth-462 (Which appears to be an Earth-X scenario-WWII still being fought in modern times, that is-but with analogs of the JLA, or maybe the Teen Titans, instead of a Freedom Force). Earths -0 annd -S are, of course, easy.

Wonder how many search hits these Earth names will end up getting me...

UPDATE
Oh, and the "New Earth" page is muy interesting. If these shards are all elements going into the new Earth...well, we have Superman having adventures of some kind when he was a boy. We have Phantom Zone Criminals. We have a white-hair-sideburns Superman involved somehow. We have Joe Chill known to be the Waynes' killer from the very beginning. We have Wonder Woman as afounding member of the JLA, and possibly Batman as well. Which would come awful close to fixing all of the mistakes made in making the first New Earth back at the end of the first Crisis...
