[seqfan] Re: First fini sequence in the table?

[franktaw at netscape.net]

By A-number, the first few fini sequences are A000053, A000054, 
A000797, A000926, A001049, A001219, A001228, A001259, A001272, and 
A001293.

On another issue, there are sequences such as A164081 that are finite 
in the sense that from some point on they are zero. I think some such 
sequences are marked "fini", while others (like A164081) just have lots 
of zeros. We really ought to have a standard for this. (If we do decide 
these should be marked finite, A000004 would  of course be an 
exception.)

As most of us know, for a long time Neil excluded finite sequences, 
though
he made exceptions for sequences not known to be infinite (e.g., 
Mersenne
primes) and "for certain important number-theoretic sequences,such as
Euler's idoneal (or suitable) numbers."

This raises the question: was A926 the first sequence in the OEIS known 
to
be finite? At what point were the keywords fini and full accepted?
