The octagon is nine hundred and fifty feet in diameter and nearly regular in shape.

It is a regular octagon in shape.

A regular octagon is regular, though an octagon in general is no more regular than any other figure.

These sockets are arranged in the form of a regular octagon, with the ninth in the middle, and are numbered consecutively from one upwards.

Make the octagon as regular as possible.

In order to illustrate what an eigenfunction for the regular octagonal group does look like, we have computed one such eigenfunction following the method exposed in .

Theorem 1.1 When s is irrational, ∆s is a ful l measure set consisting entirely of squares and semi-regular octagons.
The Octagonal PET II: The Topology of the Limit Sets
Say that an extended pyramid of size K is the union of polygons obtained by taking the outer squares in each row and chopping off the corners so as to leave semi-regular octagons.

At each of these vertices, the adjacent edge of Oj makes an acute angle with the bottom edge of Xs . (The angle is π/4.) Since the ∆s consists of an open dense (in fact full measure) set of squares and semi-regular octagons, every neighborhood of the two vertices in question must intersect inﬁnitely many tiles of ∆s .
The Octagonal PET II: The Topology of the Limit Sets
If K is a triangle, then two of the vertices v1 and v2 of K have acute angles. (The angle is π/4.) These vertices must be accumulation points of inﬁnitely many tiles, because all the tiles are squares and semi-regular octagons.
