Another result from my modified qfind:

3c/9 width-16 symmetric: 0 period-9 ships

Edit:
2c/6 width-11 asymmetric: 0 ships (confirms previously known result)

5c/10 width-11 asymmetric: 0 ships
5c/10 width-22 symmetric: 0 ships

My 2c/7 width-22 symmetric search finished, confirming that the weekender and weekender + tagalong are the only period-7 ships of this type. I ran all of the partial results found along the way through apgsearch (locally), but it didn't find anything new.

I created a modified version of qfind to generate a finite (but non-minimal) list of ships that can be used to construct all orthogonal ships of a specified period, translation, logical width, and symmetry type.

I've made a modified version of qfind to find a finite set of spaceships that can be used to construct all possible ships of a given period, translation, logical width, and symmetry type. Unfortunately, this is done very inelegantly, so it can only be used when the finite list of ships is small. I s...
