Math::NumSeq::OEIS::Catalogue -- available A-numbers
use Math::NumSeq::OEIS::Catalogue; my $anum = Math::NumSeq::OEIS::Catalogue->anum_first; my $anum_next = Math::NumSeq::OEIS::Catalogue->anum_after($anum);
This module lists the A-numbers available for
Math::NumSeq::OEIS. It includes those available from NumSeq module code and those available from files.
A-numbers are handled as strings like "A000032". Six digits is usual, though rumour has it the plan is for seven digits like "A1000000" when the millionth sequence is reached.
Add-on distributions can extend the catalogue by creating a plugin module. See Math::NumSeq::OEIS::Catalogue::Plugin for details.
$anum = Math::NumSeq::OEIS::Catalogue->anum_first()
$anum = Math::NumSeq::OEIS::Catalogue->anum_last()

$anum = Math::NumSeq::OEIS::Catalogue->anum_before ($anum)
$anum = Math::NumSeq::OEIS::Catalogue->anum_after ($anum)
Return the A-number before, or after, a given
undefif there's no more A-numbers in the respective direction.
