New description:
I guess the optional spkg {{{database_sloane_oeis-2005-12.spkg}}} could be
removed.
The package contains a {{{sloane-oeis.bz2}}} which expands to a 20.165.423
Bytes file {{{sloane-oeis}}}. This file has 113134 records (apparently
sorted by "OEIS lexicographic order"):
{{{
A000004
,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,
A112316 ,0,0,0 ...
}}}
On the other hand the module {{{\src\sage\databases\sloane.py}}} downloads
a current file {{{http://oeis.org/stripped.gz}}} (17.971.650 Bytes).
This expands to a 45.252.744 Bytes file with 236976 records (including the
4 header records):

sloane.py also downloads {{{http://oeis.org/names.gz}}} with
(8.330.058.251 Bytes (expanded 20.853.789 Bytes) and some same number of
records as strippd.gz:

{{{striped}}} contains more than double the number of sequence records
compared to {{{sloane-oeis}}}. Often the sequences have additional
elements. The new file may also contain corrected errors ...
