...so we can have spaceships that travel at the speed of 50c in Golly?

I found a 46C spaceship, but it can't be made into a a 50C spaceship because this design only works for speeds that are one less than primes.

EDIT: When I was posting this, I found that unless the extended RLE gives the pattern's coordinates, LifeViewer places the pattern in the upper left of the torus but Golly places it in the middle. This isn't a problem for tori, but the same thing also happens on a bounded grid, which causes some patterns to run differently. Fortunately this can be avoided by explicitly specifying the coordinates.
