The namesake of this object also names a formula that assigns a value of (-1)k to a positive integer n that has k distinct prime factors and also names a related inversion formula. A rectangle consisting of two 2x1 rectangles with a unit square in the middle can be used to tile it, and paradromic rings are created by deforming it. Independently discovered by Listing and its namesake, two of these constructs can be combined to form a Klein bottle. 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.
