CoDiMa is the Collaborative Computational Project (CCP) in the area of Computational Discrete Mathematics, supported by the EPSRC (EP/M022641/1).

CoDiMa is centred on two open source software systems: GAP and SageMath which are widely used for research and teaching in abstract algebra, number theory, cryptography, combinatorics, graph theory, coding theory, optimisation and search, among other areas.

The CCP aims to support the ecosystem of users, extenders and developers of these systems and encourage best practice in their use, and to support the more rapid uptake of new features such as parallel programming support.

The project run for 5 years starting from March 1st, 2015.
