Apologies for peppering you with blog posts, but here, posted on New Year’s Eve, is an even more attractive Christmas Day tessellation, Trefoil Lattice Labyrinth (25,12) in suitably icy colours. The background is Snowdon, the highest peak in Wales, seen form Crib Goch, looking and feeling on the occasion of a classic snowy traverse about three times its elevation of 1,085 metres (3,560 ft). Here in Cromford (England) snow has been lying for four days of delicious icy Alpine sunshine. Today, fog over the hills presages a thaw.
The “snowflake” includes just six supertiles,m each made of 25^2 + 25×12 + 12^2 = 1069 equilateral triangles.
