I have zero background in linguistics, so forgive me if this is trivial.

The Wikipedia article for relative clauses claims that, with regard to the positioning of the relative clause, "English, for example, is generally head-first".

However, intuitively, it makes sense that a "reduced object passive relative clause" would be able to precede the head noun. Yet, I cannot find any example online where such a case serves as an example of the usage of a reduced relative clause.

In the 2009 University of Georgia Classic City Classic tournament, this sentence appears in one question:

> Formed by reattaching the ends of a closed band after cutting the band and giving it a half-twist, name this structure named after a German mathematician, a one-sided, nonorientable surface.

Of interest is this:

> Formed by reattaching the ends of a closed band after cutting the band and giving it a half-twist

Hence my question: can reduced relative clauses precede a head noun, or if not, what sort of grammatical structure is this?

Academic sources would be appreciated.
