Typically if a sequence is wrong but existed for a long
time before that was discovered, it gets all the information
stripped out but leaves a tombstone behind with the
erroneous sequence data.  Search for keyword:dead
or erroneous to find examples.

That said, I'm skeptical about this one being wrong.
I'd want to be very sure before asserting that the data
given (396204) is wrong, since the sequence data
appears to have gone unchanged since the 1973 book.
