John,
Many Thanks for support! Now I have all information which I need on the
start.
About Integer factorizations Will be worthy to implemented to SAGE probe
factorization with prime base to safe computer time.
best wishes

Tell me yet is possible to count rank of my curve over rational field
I was try
E.mwrank

It might help you to know the following:
The TAB key can provide information about what possibilities are available from the
string that you have just typed. As you have discovered, if you type a "partial
string", TAB will give you completions that are known.
TAB following the "." will give you names of both methods (functions) and variables associated to
the name you have just typed, as for "E.". Not all names will work for a given instance; what will
actually work depends on exactly how the instance was created (Sage is based on Python [see below], which has
a good "object" structure underlying it).
Also, once you have a complete name, "?" and "??" will give you documentation ("?") or documentation +
implementation (if possible) ("??") for the name. Try typing "E?", once you have defined E as an elliptic curve (you
get the same with "Elliptic_Curcve?").
It may also be helpful to review documentation on Python, and its "class" structures
(see the documentation link on<http://www.python.org>). Python is the underlying
language for both the Sage system and the Sage interpreter, so understanding that will help you
to understand Sage.
We don't put all of the possible details for all of Sage's functions and classes into
documentation at any one time; Sage is dynamically changing, and to do so would be a lot of
work. Instead, we rely on the above "on-line" mechanisms to supplement the
documentation. A fair amount is automatically culled from source and put into various manuals
(cf the documentation available in your installation, or on-line at<http://sagemath.org>).
Finally (if you've gotten this far), your experience with "mwrank" shows that this is a
method, i.e., a function/procedure. Typing "E.mwrank?" will give you information about
how to use it.
