Re: 31c/240 caterpillar working notes

Unfortunately this rake works out to be an R4L9F, so this is spectacularly non-useful (because a rephaser plus a regular forerake is an R2L9F, much simpler and less than half as expensive). The R2L16 is firing on lane (16 + 2*9) mod 31 = 3, and the kickback bumps it up +6 lanes, which is very close...

Re: 31c/240 caterpillar working notes

Continuing on with the idea of adding extra backrakes at the front in order to save time later on: 3 backrakes in front, even before the double rake then double rake with 4 backrakes inside it, aligned to lane 7, we have 7R to work with 4B + R3L28 (hits lane 0, aligned to lane 3, now have 4R to work...

Re: 31c/240 caterpillar working notes

I just wanted to point out that we can fit at least 4 back rakes within the "diamond" that comes before the double forward rake at the beginning. These would be essentially for free. I wanted to use this location to produce the back rakes in point 2 of my previous post but using them for kickbacks ...

Re: 31c/240 caterpillar working notes

Apologies for the double post. Here is an updated optimal lane rake table, taking into account the fact that we can do double kickbacks via backward rakes farther up in the silverfish (2 backrakes/rephasers per double kickback). Note that some of the double kickback via backrake entries here are sub...

Re: 31c/240 caterpillar working notes

Taking the double kickback idea into account, here is a new table of optimal rakes for each lane. It makes use of the following new rakes: R4L8 = R2L23 + double kickback R5L13 = R3L28 + double kickback R7L29 = R3L28 + two double kickbacks No other double kickback rakes are helpful here, as far as I ...

Here is a table of the shortest way of putting a glider on a particular lane (starting from lane 0), now that we have R3L28: Lane: Rake 0: R1L0 1: R2L23 + 1 rephaser 2: R3L28 + 4 rephasers 3: R2L25 + 1 rephaser 4: R6L17 + 2 rephasers 5: R1L0 + 4 rephasers 6: R3L28 + 1 7: R3L28 + 8 rephasers 8: R2L25...

Awesome! Only issue is by default it leads to the "no rule specified" page; is there an option to default the rule parameter to b3s23?
Done! It now defaults to b3s23 if no rule is specified.
