I have suppressed the tag "almost-periodic-function" which is an analysis category having nothing to do with tiling

This hexagon-with-dents is a tile which, I think, tiles the plane in a necessarily aperiodic way:

     ________  __ 
    /        \/  \__
   _\              /
  /                \
 /                  \
/                    \
\                    /
 \                  _\
  \                /
  /_              /
    \_/\_________/

IsThis is essentially the Socolar–Taylor tile. I'm rather surprised that this tile does not appear in the paper of Socolar and Taylor, and that it also doesn't appear in Wikipedia's list of aperiodic sets of tiles.

Did I miss something?
Am I maybe wrong to claim that this tile tiles the plane in a necessarily aperiodic way?

Question: Does the above tile tile the plane in a necessarily aperiodic way?

An aperiodic hexagonal tile?
