Diagonal Puffer

x = 16, y = 16, rule = R2,C3,M1,S6..10,B7..8,NM

1. I guess, this was thefirstpuffer discovered in range > 1 in "non-relativistic" rules

by the way, how to define "non-relativistic" for ranges greater than 1:

I spent yesterday trying.

what I know for sure is: R2,B7 seem to me quite different from R2,B5 ...

... as R1,B3 is quite different from R1,B2

EDIT: or maybe I should call R2,B7 rules with spaceships : "rules

*with*bugs" ?

R2,B5 .... "rules

*without*bugs" ?

e.g. compare spaceships

BTW,

I am probably able to prove (weak) upper limits on the speed of:

A) info transfer

B) orthogonal ships

in rules with any range R, minimal birth Bmin, and width W of the stripe that covers the ship,

with assumptions:

* finite pattern

* infinite space

* long distances

* orthogonal speed

the proofs need to simulate a "covering-rule" e.g.

for R2,B7, the covering-rule is R2,C2,M0,S0..24,B7..24,NM

Code: Select all

```
x = 5, y = 5, rule = R2,C0,M0,S0..24,B7..24,NM
5o$5o$5o$5o$5o!
```

Code: Select all

```
x = 5, y = 5, rule = R2,C0,M0,S0..24,B7..24,NM:P100,5
5o$5o$5o$5o$5o!
```

----

for B6 the same results

the covering-rule is R2,C2,M0,S0..24,B6..24,NM

----

for B5

the covering-rule is R2,C2,M0,S0..24,B5..24,NM ;

With the assumptions above, any rule R2,B5 probably cannot transfer info faster than 1.5*c;
