Elementary Knightship found in Conway's Game of Life
Context: a knightship is a glider (a structure that translates itself across the Life grid periodically) which moves 2 horizontal units for each 1 vertical unit (or vice-versa if rotated). This is in contrast to e.g. the most popular 3x3 glider which moves diagonally (1 for 1). A knightship is a type of oblique glider - one that doesn&#x27;t move orthogonally (only horizontal&#x2F;vertical) or 45º diagonally.<p>What makes this an <i>elementary</i> knightship is that it isn&#x27;t built out of smaller discrete components, unlike (for example) the oblique glider Waterbear (<a href="http:&#x2F;&#x2F;conwaylife.com&#x2F;wiki&#x2F;Waterbear" rel="nofollow">http:&#x2F;&#x2F;conwaylife.com&#x2F;wiki&#x2F;Waterbear</a>). It&#x27;s the first elementary oblique glider discovered.<p>It also happens to move exactly 2 vertical units for each 1 horizontal unit of motion, and carries this out in 6 time-steps (the theoretical minimum). Thus, in some sense it has the simplest movement of any possible knightship.
