axialaxial
Axialaxial is a term used in geometry and related design contexts to describe objects or patterns that exhibit symmetry with respect to two principal axes. The word is a neologism formed by repeating axis-related language to emphasize dual-axis symmetry, and it is not a standard or formal term in mathematics. In informal use, axialaxial refers to shapes or tilings that remain invariant under reflections across two distinct axes, typically intersecting at a central point.
In two dimensions, an axialaxial figure possesses two lines of symmetry. When those axes cross, the figure
In three dimensions, axialaxial symmetry can describe objects invariant under reflection across two orthogonal planes or
Because axialaxial is informal, precise usage varies, and many authors prefer to describe the exact symmetry
