Hello Martin As promised (before vacation) below two examples which I'm unable to interpret (otherwise I recognized that you've improved your code and that it's now included in fricas -- great :). A lot more examples work now (i.e same results as Kenzo).
BTW: why didn't you allow '0'? NNI=0,1,2,... ;) -- from https://www-fourier.ujf-grenoble.fr/~sergerar/Kenzo/Kenzo-doc.pdf --- ASIMP := FiniteSimplicialComplex(VertexSetAbstract) v0:List(List(NNI)) :=[[0],[1],[2],[3],[4],[5],[6],[7], _ [0,1],[0,2],[0,3], _ [0,4],[0,5],[0,6], _ [0,7],[1,2],[1,3], _ [1,4],[1,5],[1,6], _ [1,7],[2,3],[2,4], _ [2,6],[2,7],[3,4], _ [3,5],[4,5],[4,6], _ [5,6],[5,7],[6,7], _ [0,1,5],[0,1,6],[0,1,7], _ [0,2,3],[0,2,4],[0,2,6], _ [0,3,4],[0,5,7],[1,2,3], _ [1,2,4],[1,2,7],[1,3,5], _ [1,4,6],[2,6,7],[3,4,5], _ [4,5,6],[5,6,7]] -- Dunce hat -- https://en.wikipedia.org/wiki/Dunce_hat_(topology) v1:List(List(NNI)) :=[[1],[2],[3],[4],[5],[6],[7],[8], _ [1,2],[1,3],[1,4], _ [1,5],[1,6],[1,7], _ [1,8],[2,3],[2,4], _ [2,5],[2,6],[2,7], _ [2,8],[3,4],[3,5], _ [3,7],[3,8],[4,5], _ [4,6],[5,6],[5,7], _ [6,7],[6,8],[7,8], _ [1,2,6],[1,2,7],[1,2,8], _ [1,3,4],[1,3,5],[1,3,7], _ [1,4,5],[1,6,8],[2,3,4], _ [2,3,5],[2,3,8],[2,4,6], _ [2,5,7],[3,7,8],[4,5,6], _ [5,6,7],[6,7,8]] dunceHat := simplicialComplex(vertexSeta(8::NNI),v1)$ASIMP homology dunceHat -- [Z,Z*24,0] , actually H0=Z, others 0. -- Diabolo v2:List(List(NNI)) := [[1],[2],[3],[4],[5],[6], _ [1,2],[1,3],[2,3],[3,4],[4,5],[4,6],[5,6], _ [4,5,6]] diabolo:= simplicialComplex(vertexSeta(6::NNI),v2)$ASIMP homology diabolo -- [Z,Z*4,0] , actually H0=Z, H1=Z, H2=0.
