HPCombi
11+
=======
12+
13+
This page describes the functionality from `HPCombi`_ available in
14+
``libsemigroups_pybind11``. This functionality is only available if
15+
:any:`LIBSEMIGROUPS_HPCOMBI_ENABLED` is ``True``. `HPCombi`_ provides high
16+
performance (SIMD accelerated) partial transformations, transformations,
17+
permutations, and partial permutations on up to ``16`` points. The classes
18+
implementing these element types belong to the ``hpcombi`` subpackage of
19+
``libsemigroups_pybind11``, and can be used with the ``libsemigroups_pybind11``
20+
classes:
21+
22+
* :any:`FroidurePin`
23+
* :any:`Konieczny`
24+
* :any:`SchreierSims`
