velcrorex wrote:What program did you use to do your searches?

I used WLS at a height of 11 to find the wings. I wasn't making a point of being thorough at the time, so I only saved patterns that 'looked promising' to me. I then copied the result and flipped it to point towards the upper left while giving it some sort of symmetry (glide or bilateral). I then extended the search area perpendicularly away from the wings.

I found this spaceship with a simple short, wide search, but it is clearly composed of two wings supported by a (very small) central component. By separating the wings a little more and performing a search similar to the one described above, I managed to find the following pushalong to Jason Summers' small spaceship:

`x = 74, y = 74, rule = B3/S23`

The trick seems to be in finding potential wings. It seems that components that have only 'loose' connections to other components are the most promising, as they can connect to a large number of other components, and so provide more area for searching. By "loose connection" I mean that they only react with other components in a very simple way and only for a few generations.

I wrote:Seal and seal pulling its one known tagalong are the only other known c/6 diagonal spaceships.

I was not quite correct here. Two seals are able to interact nontrivial (but not in any interesting manner). This allows the construction of infinitely many c/6 diagonal spaceships (obviously, yours is only the third interesting c/6 diagonal spaceship):

`x = 37, y = 61, rule = B3/S23`

Unfortunately, this new spaceship doesn't seem to have any sparks that are useful for perturbing gliders; however, I hope that the new spaceship will open up this area for more discoveries.

Somewhat off-topic: When I was testing collisions between the new spaceship and gliders, a strange still life occurred as the spaceship decayed:

`x = 36, y = 39, rule = B3/S23`
