I guess there is no off-topic on this thread.
These guys show similar but opposite features (squinted eye, larger nostril, etc.) My twin daughters also have exact opposite features, although more subtle (and prettier!!). Teeth came in and fell out in opposite manners from each other, eye dominance (for shooting), etc.
Not really, no. We are the unsorted detritus of discussion groups, united only in finding unexpected juxtapositions of incongruities, which tentatively stimulate our amusement in mild ways for short periods of time.
That, and sharing our common commonalities, the "I know, you know?" characteristics of being supposedly human. These unending banalities form a continuum of faint titillation which is our customary abode, the Undead Thread.
For example, your online ID, "21twelve" is a mathematical palindrome, and twelve times twelve and twenty-one times twenty-one are also mathematical palindromes.
That is, 12 x 12 = 144 and 21 x 21 = 441.
Interestingly, 13 x13 = 169 and 31 x 31 = 961 but that's as far as it goes in base ten math.
Good Morning!
Are they mirror symmetric inside as well?
