Re: (Engineered) diehards

Hi All, The following 112 X 89 diehard has two more levels to the tetration before the second fuse light. Its lifetime should be lower bounded by 13^^^3: x = 112, y = 89, rule = B3/S23 5b3o85b4o$7bo42b2o49b2o4bo$6bo24bo3b2o3b2o9bo33b2o8b2o4bo4bobo$30bobo 2bo4bo2bo7bobo6b2o22b2o5b2o9bo4bobo$31b2o3b3o...

Re: (Engineered) diehards

Hi All, On my first post to this thread I mentioned that I tried to start the diehard by sending a glider over the top and that I couldn't get it to work. I found a way to make that work: x = 112, y = 89, rule = B3/S23 2o19b8o20b12o4b5o2bo15b2o15bo$b2o19bo4bo22bo3b2o8b2obob4obo13b2o8b2o5b o$o43b2o4b...

Re: (Engineered) diehards

Hi All, I appreciated Calcyman's suggestion to use the empty space to put some tubs back. I investigated this and it turns out that triggered still lives that deposit something a distance away, while avoiding obstructions are extremely rare. This is due to the explosive nature of anything that moves...

Re: (Engineered) diehards

Hi All, I saw toroidalet's failed example of using a blockic. I noticed that little white dot turning a tub to a boat. So I investigated what was going on. I found the apparently excellent long tub with tail block destroyers were the bomb in more ways than one (they have a pitch of 3 diagonals, and ...

Re: (Engineered) diehards

Hi All, I was thinking that it would be really nice to do a few first sawtooth pulls before lighting the first fuse. Also, as Toroidalet noted the the delays down and to the left of the three glider collision are the least valuable use of area (except the vast open space with nothing in it). So I th...

Re: (Engineered) diehards

Re: (Engineered) diehards

Hi All, Toroidalet wrote Speaking of, I don't really see any ways forward at the moment. It looks like we'll need a miracle for any ignition reaction we have to fit inside y=89; the closest is the +4 crabstretcher-tail-tub-with-tail, which will maybe get us to 90 if we find a new cleanup with the ri...

Re: (Engineered) diehards

b3s23love: And I was incorrect about your contribution. The 507 is the number of loaves and you increased their number by 10, so you increased a 497 in the equation to 507. This also means that I was incorrect in my estimate of the second fuse loaves with my inclusion of 2 toads. It should be 121^(1...

Hi All, I found a way to ignite a fuse with a pull. The configurations of still lives that do the lighting are actually fairly common. The difficult parts in getting it to work were working around the unmovable eater (required for C/5 spaceship destruction) and getting the phase right so the burn te...

Hi All, So, I speculated as to what the minimum area that could be achieved to create an exponential diehard. I feel a proper exponential diehard would be based on Sawtooth195. So I set about making a diehard out of Sawtooth195. The most difficult part of the construction of a diehard is the destruc...

I recently upgraded my knightt search program to do the various period doubling symmetry modes. For example, this means I can now search for 2c/6 spaceships of glide, even, odd, and gutter symmetries by modifying my c/3 search mode. Since knightt (if run to completion) finds a complete representativ...
