Hey! Thanks for raising these questions. This list is more for questions about Sage usage, so I forwarded your question to sage-devel, a more natural place to discuss it. For anybody interested, the discussion is at: https://groups.google.com/d/topic/sage-devel/i9ubOqBWDLA/discussion Best, Sa

2016-09-09 Thread Albert Haase
For an abstract finite simplicial complex C, the method homology(algorithm='auto',generators=True) uses CHomP to compute the homology groups and their generators. The generators are conveniently expressed as sums of simplices from C rather than as coefficient vectors of chains from the chain co
