17c/45 Spaceship, Part 4 (Appendix)

This appendix contains some miscellaneous patterns and additional information, which may or may not be useful in this Spaceship project.

There are several backward rakes known that use only two trails, with various separations between the trails:

Here's a simple backward LWSS rake:

Here's a simple way to convert from separation 28 to 29:

Here are some ways to delete one of a pair of blinker trails (there are others):

Here are all the ways I know of that a passing pi can turn a simple stationary object into a glider. Note that only two of them generate forward gliders.

Here's how a glider can be reflected by a pi. Note that there are no backward-to-forward reflections.

A few miscellaneous reactions:

Blinker repositioning

• Analysis of the expected size of the Spaceship
• Tips for aligning gliders
