OSOApb

A Hadamard matrix in m runs is used for creating an OSOA in n=2m runs for at most m-2 columns.

internal

Creates stratum orthogonal arrays (also known as strong orthogonal arrays). These are arrays with more levels per column than the typical orthogonal array, and whose low order projections behave like orthogonal arrays, when collapsing levels to coarser strata. Details are described in Groemping (2022) "A unifying implementation of stratum (aka strong) orthogonal arrays" <http://www1.bht-berlin.de/FB_II/reports/Report-2022-002.pdf>.

<dl><dt>m</dt>
<dd>the number of columns to be created;
if <code>n</code> is also given, <code>m</code> must be compatible with it</dd>
