Description

These combinatorial objects index the space of symmetric polynomials in two sets of variables, one commuting and one anti-commuting, and they are known as symmetric functions in super space (hence the origin of the name super partitions).

Super partitions may be input in two different formats: one as a pair consisiting of fermionic (strict partition) and a bosonic (partition) part and as a list of integer values where the negative entries come first and are listed in strict order followed by the positive values in weakly decreasing order.

A super partition is displayed as two partitions separated by a semicolon as a default. Super partitions may also be displayed as a weakly increasing sequence of integers that are strict if the numbers are not positive.
