… that all orthogonal spaceships with the unsimplified speed c/n are known to exist in range-1 isotropic rules? (True period c orthogonal, c/2 orthogonal and c/3 orthogonal spaceships are known in various rules, and can be constructed for all c/n speeds where n is even and greater than 3, and also where n is odd and greater than 4.)
