Dr Emmanuel Sapin is currently an Associate Research Fellow at Exeter University in the UK. Here is a large collection of guns that he found and ran on the Life32 simulator. There are 15,363 guns from 15,134 unique rules in the collection. I coded a Non Totalistic rule family so that I could run them on my Square Cell simulator.

The gun collection is here:

http://bprentice.webenet.net/Emmanuel%20Sapin/

and my simulator is here:

http://bprentice.webenet.net/Square%20Cell/

To run the guns load the first one, gun0.sqc, and step through the remainder using the Page Down key.

Perhaps a member of this list will code rule specifications so that the gun collection can be run and explored with Golly.

To see the guns with Golly, and to generally experiment with non-totalistic rules using Golly, see:

viewtopic.php?f=11&t=936#p6836 (and the rest of my overly wordy posts in that thread)

and

viewtopic.php?f=9&t=933#p6815

The scripts let you enjoy all of Emmanuel Sapin's spaceship guns and more. Below, I'm including the ruletable, for Sapin's Rule R which he proved to be universal by emulating Life (B3/S23).
It is worth taking a moment to scribble in Rule R -- you'll see guns form very readily.

Thanks to the amazing Paul Tooke, here are some "non-natural" ships that work in rule R:
x = 140, y = 21, rule = s2eki3-ek4cvqjz/b3-ekyj4-j5-evqr68

Dr. Sapin was very surprised when I sent the above to him.

If anyone constructs a rake in Rule R, please post it! Thanks!

Note to Brian: I've got a backlog of CA work which could be considered a response to several contributions you've made to this forum. I'll try to get it all together and start posting more of it here.

As a python apprentice, I spent an hour writing a piece of code —

Code: Select all

a = []
for i in range(0,15363):
    name = 'D:/test/Emmanuel_Sapin_15K_alien_guns/gun' + str(i) + '.rle'
    with open(name,'r') as file_object:
        textlist = file_object.readlines()
        for text in textlist:
            if 'B' in text:
                rulestring = text.split(" ")[-1]
                a.append(rulestring)

for k in range(0,15363): 
    with open('D:/test/Emmanuel_Sapin_15K_alien_guns/census.txt','a') as file_object:
        file_object.write(str(a[k]))

— that goes through the RLEs in this gun collection and records the rulestrings. The result:

census.txt: (805.26 KiB) Downloaded 90 times

In the process I noticed that there are at least two duplicates, as listed below.
Gun11842.rle:

Code: Select all

x = 9, y = 9, rule = B2cn3ary4acijrtz5iknqr7c/S2aci3aejqr4-cintw5cy6-e8
obo$6bo$5b3o$5b3o$4b2ob2o$4bobobo$5bobo$5b3o$5bobo!

Gun11846.rle:

Code: Select all

x = 10, y = 9, rule = B2cn3ary4acijrtz5iknqr7c/S2aci3aejqr4-cintw5cy6-e8
8b2o$2bo5bo$b3o$b3o$2ob2o$obobo$bobo$b3o$bobo!

Gun5404.rle:

Code: Select all

x = 4, y = 3, rule = B2c3aejy4ijnqry5-ekqr6ack7c/S2ai3cejnq4ajkrtwy5knqy6-ik
4o$3o$4o!

Gun5407.rle:

Code: Select all

x = 3, y = 8, rule = B2c3aejy4ijnqry5-ekqr6ack7c/S2ai3cejnq4ajkrtwy5knqy6-ik
o2$o3$2o$b2o$2o!

There may be more duplicates that are less trivial, for instance same evolutionary sequence with different rulestrings. Should we clean it up?
