I haven't been able to find any information of a practical
use for a 25
mark ruler specifically. I don't believe that the
applications for
example of 4 mark rulers would benefit from an improved 25
mark ruler. I
could be completely wrong of course (and actually I kind of
hope that),
but I think it would be a part for the Dnet folks who write
project
documentation to dig into that.
Now the introduction only contains very general references
of what OGRs
could be good for ("OGR's have many applications
including sensor
placements for X-ray crystallography and radio astronomy.
Golomb rulers
can also play a significant role in combinatorics, coding
theory and
communications"), but nothing particular to how this 7
year long project
could advance the field when actually completed.
I understand it's possible that no practical uses for this
information
have yet been identified, placing it only inside basic
research.
However, if some such planned or even potential uses have
been
identified, for example since OGR-25 started, then the
project
description should definitely have more information about
them.
