I borrowed a book from Wythoff about Dutch genealogy.

The mathematicians cataloged several Wythoffs while studying impartial combinatorial games.

In the seminar, we examined various Wythoff constructions to understand their combinatorial properties.

In the lecture, the professor demonstrated the Wythoff construction to show how uniform polyhedra and plane tilings can be generated from symmetry operations.

She introduced a Wythoffian construction to generate Beatty sequences with specific combinatorial properties.
