22 - dotseedstar number series

22 and symmetry: let's take a closer look - digits, even, factors, matching, symmetry, mathematical operations, 1 as the identity for multiplication and division, 0 as the identity for addition and subtraction, 1 as an exponent, math transformations, translation, slide, reflection, flip, rotation, turn, dilation, resize, line of symmetry, bilateral symmetry, bi = 2, lateral = side, rotational symmetry, order of rotational symmetry, regular polygons, degrees of a circle, vertex, relationship between rotational symmetry, division, and degrees of a circle. Phew! 22 has a lot going on.
