  • Ticket #17922 – Description

    initial v4  
     1The different behaviour between the two rings consists of
     2 1. the `coefficients(sparse=True)` (which is default) method returns a list of pairs in `SR`, and a list in `PolynomialRing`,
     3 2. `Expression.dict()` does not exist.
     4Example:
    15{{{
    26y = 3*x^3 + 2*x^2 - 4*x
