Abstract

Abstract A puzzle in which each of a number of regular octagons is divided to form an irregular octagon and a number of smaller pieces. Each irregular octagon has four pairs of equilateral parallel sides. Each of the smaller pieces has two pairs or three pairs of equilateral parallel sides. The sides of all parts formed are equal in length. A number of the pieces are capable of being assembled in juxtaposition to form a large regular octagon, which assembly can be performed in a large number of different ways.

Claims Analysis

Total Claims: 15
Claim 1
Independent Claim 55 words
A puzzle comprising a plurality of pieces adapted to be juxtaposed to form a regular octagon, said pieces being formed by subdividing a number of blocks having the shape of a regular octagon to form a group of parts, which group includes a number of irregular octagons, said pieces comprising a number of said groups.
Claim 2
Dependent Claim 55 words
A puzzle comprising a plurality of pieces adapted to be juxtaposed to form a regular octagon, said pieces being formed by subdividing a number of blocks having the shape of a regular octagon to form a group of parts, which group includes a number of irregular octagons, said pieces comprising a number of said groups.
Claim 3
Dependent Claim 27 words
A puzzle as in claim 1 in which each part has the form of a multilateral geometric figure, the juxtaposed sides of which have the same length.
Claim 4
Dependent Claim 20 words
