Reverse Lexicographic Order
In a common variation of lexicographic order, one compares elements by reading from the right instead of from the left, i.e., the right-most component is the most significant, e.g. applied in a rhyming dictionary.
In the case of monomials one may sort the exponents downward, with the exponent of the first base variable as primary sort key, e.g.:
- .
Alternatively, sorting may be done by the sum of the exponents, downward.
