What does work is 1-13-3. It's close enough that Track Designer will
consider it a closed loop.
You can turn it into a triangle with a 5-13-7-12-4-5 pattern (starting with
curves and alternating with straights). Then it's easy enough to see that
it forms a lesser know Pythagorean triplet, 5-12-13. The angle formed by
short leg and the hypoteneuse is 22.62 degrees, which matches very close to
the curve track being 22.5 degrees.

Oops. That should be the long leg and the hypoteneuse.
