ECM Factorization. Download our free command line tool (64-bits)
We implementated our own version of Lenstra's elliptic curves method. We make use of python's multiprocessing module to try multiple curves at the same time and we are using gmpy2 for fast arithmetic computations.
The biggest number we factor so far is rsa-79 from Paul Zimmermann's challenges.
Currently, you can only get a command line WIN64 through our installer that you can get below
Win 64-bit version here:
setup_ecmpy-amd64.exe (4.1MB).

Understanding MBSE
IKASIGOGAILUA. MBSE. A little exe from AA55 consulting
Please go to get an helper, which will give you access to a GUI explaining step by step how to build complex systems from scratch. Several instructive examples are given.
Because it is always difficult to understand where to start in complex system designs, we created this little application to help you understanding the different steps that allow you to describe a complex system. What is the right break-down, etc...

A gift from AA55 consulting
Please download and check out setuplsystemV0_9.exe (15MB), which is a GUI for drawing L-systems
You are welcome to comment or report bugs to lsystem@aa55.fr
lsystem is a graphical user interface for drawing L-system images.
An L-system consists of an alphabet of symbols that can be used to make strings, a collection of production rules that expand each symbol into some larger string of symbols, an initial "axiom" string from which to begin construction, and a mechanism for translating the generated strings into geometric structures. L-systems were introduced and developed in 1968 by Aristid Lindenmayer.
A look at the application window:
Below a 3D Hilbert cube, made from the commercial version of software application. This application has its STL file building menu enabled
The application can be downloaded on demand by emailing to lsystem@aa55.fr
