thumb|A geometrical hexafoil
The hexafoil is a design with six-fold dihedral symmetry composed from six vesica piscis lenses arranged radially around a central point, often shown enclosed in a circumference of another six lenses. It is also sometimes known as a "daisy wheel". A second, quite different, design is also sometimes referred to by this name; see alternate symbol.
