* Sectors and Grids
Systems are divided into sectors, and sectors into grids. Both
divisions use the same scheme with units numbered 1 - 400:
|-----+-----+-----|
| 1 | ... | 20 |
|-----+-----+-----|
| 21 | ... | ... |
|-----+-----+-----|
| ... | ... | 400 |
|-----+-----+-----|
* Distance Computation
** Given galactic coordinates (x, y), find system ID s.
s(x,y) = 20 * y + 120 + x + 7
= 20y + x + 127
** Given system ID s, find galactic coordinates (x, y) where:
x(s) = (s - 127) % 20
y(s) = (s - 127) / 20 (integer division)
** Given two systems s1, s2, find distance in galactic coord. units.
d(s1,s2) = sqrt((x(s1) - x(s2)) ** 2 + (y(s1) - y(s2)) ** 2)

* Travel Time
Travel time (turns) in the game by either Light Speed or Hyper Jump
is not geometrically proportional to displaced distance, so the above
distant calculations are only an approximate guide to travel time
between two game locations.
** Intersystem Travel
Travel time is determined by concentric shells centered on the system
of origin. Travel time is the same for any destination system in a
given shell.
Travel time to a given shell depends on method of travel (Hyper Jump
or Light Speed), engine spec., crew, etc.
For travel by Hyper Jump or Escape Pod Light Speed, there is a time
savings for moving one shell at a time instead of traversing two or
more shells in a move. For single-shell moves, there is an additional
time saving for oblique moves over orthagonal ones.
Intersystem travel time is the same for all sectors and all grids in
the destination system, regardless of the means of travel.
*** Hop count
Since there is a time savings for single-shell hyper jumps over
multi-shell, the system hop count will be proportional to the minimum
travel time between points in different systems.
**** Given two systems s1, s2, find hop count h.
dx = |x(s2) - x(s1)|
dy = |y(s2) - y(s1)|
h = max(dx,dy)
(use h instead of gf in calculating trade profitability on
intersystem runs: profit per hop.)
** Intrasystem Travel
For a given starship, engine, and crew, Hyper Jump travel time is the
same to any other sector and grid in the same system.
When travelling between sectors, the number of turns required is the
same for any grids in the origin and destination sectors.
? How to determine light speed travel time factor between two
grids/sectors?
- Within a sector, grid travel turns is equal to the number of shells
traversed.
? What is ratio of sector/grid travel time to single-system hop?

| Distance | Light Speed | Hyper Jump |
| 1 grid shell | 1 turn | 79 turns |
| 1 sector shell | 10 turns | 79 turns |
| 1 system shell | 506 turns | 99 turns |
