Schoen's H'-T surface

Half of a fundamental piece of the H'-T-surface sits in right prism over an equilateral triangle, with handles extending to the 5 faces of the prism. Similar as for the P-surface, the height of the box cannot grow arbitrarily, and the family limits either in a foliation by horizontal planes or in singly periodic Scherk surfaces.
