similar to
{{{
graphs.some_graph
}}}
or to
{{{
codes.some_code
}}}
(and similar), I propose to introduce
{{{
sequences.some_sequence
}}}
which should provide a unified access point to all possible sequences in
!SageMath. For example, there is {{{fibonacci_sequence}}} in
{{{sage.combinat.combinat}}}, {{{binary_recurring_sequence}}} (somewhere
in combinat) and various other code.
One motivation for creating this, is to include here many sequences, which
can be calculated term-by-term (from the previously calculated ones, i.e.,
recursively) or where the first N terms can be calculated at once
efficiently.
Nevertheless, it can also provide an interface to sequences, where each
term can be calculated explicitly (without dealing with the previous
ones).
