Dear all, If I have a list, how do I obtain the cardinality of the list, the command Cardinality() doesn't seem to always work. For example, the following code produces a set ComSet of sets of combinations.
Rows=3 RowVector=[2,3,2] ComSet=[] for j in range(Columns): C=Combinations(range(Rows),RowVector[j]) ComSet.append(C.list()) show(ComSet) However using Cardinality() on ComSet does not seem to work: ComSet.Cardinality() Basically I am looking for the mathematica command "Length". Furthermore how would I be able to map that command on to the elements of ComSet?
