### Random information on the term “Erector __”:

Anchor Stone Blocks (German: Anker-Steinbaukasten) are components of stone construction sets made in Rudolstadt, Germany, marketed as a construction toy.

Anchor Stone pieces originally were and are still made of a mixture of quartz sand, chalk, and linseed oil (German Patent 13,770; US Patent 233,780), precisely pressed in molds so that they fit together perfectly. The stones come in three colors in imitation of the red brick, tan limestone, and blue slate of European buildings.[citation needed] They are not recommended for play by children under 3 years of age because of their small size (CE No. 0494).

Anchor stones originated with the wooden building blocks which were designed by Friedrich Fröbel, the creator of the Kindergarten system of education. He had observed how children enjoyed playing with geometrically shaped blocks.[1]

In mathematics, a set is a collection of distinct objects, considered as an object in its own right. For example, the numbers 2, 4, and 6 are distinct objects when considered separately, but when they are considered collectively they form a single set of size three, written {2,4,6}. The concept of a set is one of the most fundamental in mathematics. Developed at the end of the 19th century, set theory is now a ubiquitous part of mathematics, and can be used as a foundation from which nearly all of mathematics can be derived. In mathematics education, elementary topics from set theory such as Venn diagrams are taught at a young age, while more advanced concepts are taught as part of a university degree.

The German word Menge, rendered as “set” in English, was coined by Bernard Bolzano in his work The Paradoxes of the Infinite.

A set is a well-defined collection of distinct objects. The objects that make up a set (also known as the set’s elements or members) can be anything: numbers, people, letters of the alphabet, other sets, and so on. Georg Cantor, one of the founders of set theory, gave the following definition of a set at the beginning of his Beiträge zur Begründung der transfiniten Mengenlehre:[1]
