grammar - a set of rules used to describe an infinite number of ways
  that one can connect a set of parts to build one large oscillator,
  still-life, or spaceship.

grandfather pattern - any pattern that can precede a given pattern
  by exactly 2 generations.

gun - any pattern that grows forever by emitting spaceships.

HashLife - a Life algorithm that achieves remarkable speed by
  storing sub-patterns in a hash table, and using them to skip
  forward, sometimes thousands of generations at a time.  HashLife
  takes tremendous amounts of memory and can't show patterns at
  every step, but can quickly calculate the outcome of a pattern
  that takes millions of generations to complete.

hassler - an oscillator that can alternately change a properly
  placed object, and then change it back.

hexlife - an alternative game similar to Conway's, which is played
  on a hexagonal grid.  No set of rules has yet emerged as uniquely
  interesting.

HighLife - an alternate set of rules similar to Conway's, but with
  the additional rule that 6 neighbors generates a birth.  Most of
  the interest in this variant is due to the replicator that evolves
  from:

lightspeed wire - a wick that can burn non-destructively at the
  speed of light, which might be useful for sending a signal or
  constructing oscillators with periods not currently attainable.
  Unfortunately, no way has been found to return a signal to its
  starting point, either by reflecting it or bending it around a
  corner.  Example:

  generated orthogonal to the direction of motion of the puffer.
  Some types of line puffers appear to be extensible and have
  arbitrarily large periods, but this has not been proven.

  very long time.  Not used to describe objects that are known to
  grow forever.  Originally defined as a pattern having a population
  of at most 10 and a Life-span of at least 100.  Examples: acorn,
  bunnies, rabbits.

period - the number of generations it takes for an oscillator to
  repeat, or a spaceship to be displaced exactly.  Often the
  notation pN is used, for example, p2 for period 2. Also, pN/m when
  symmetry is involved, where m is the number of translations; for
  example, p6/2 describes a period 6 flipper.

  yet lives forever.  Example:
