Description: The oddness of a signed permutation.

The direct sum of two signed permutations $\sigma\in\mathfrak H_k$ and $\tau\in\mathfrak H_m$ is the signed permutation in $\mathfrak H_{k+m}$ obtained by concatenating $\sigma$ with the result of increasing the absolute value of every entry in $\tau$ by $k$.

This statistic records the number of blocks with an odd number of signs in the direct sum decomposition of a signed permutation.
