Our hall bathroom was 64 years old when we had it remodeled.  It has several nice features.  One of them is this accent tile in the shower/bathtub.  Day after day, I wondered how many tile patterns there are, and how they were arranged from the stock material.  There was an extra piece of the material saved in the garage.  I finally gave in and counted the tile patterns.

Sharper eyes than mine have pointed out one of the tiles does not have 90 degree rotational symmetry.  I also was informed this is a Daltile product named Sublimity, Power Sequence (SB60) seen  here .   The less symmetrical tile appears twice in the panel.  In our shower, it appears  10 times, twice in the orientation on the left below,  and 8 times as shown on the right.
