I think it's name is actually Brian 6.

In this kind of generations rules it's not hard to find rakes such as these

Code: Select all

x = 43, y = 30, rule = 6/246/3
10.AB$8.AB$6.AB$4.AB$2.AB$.AB.AB$AB4.AB$AB5$41.AB$39.AB$37.AB$35.AB$
33.AB$32.AB.AB$31.AB4.AB$31.AB6.AB$40.AB5$4.AB$2.AB$.AB.AB$AB4.AB$AB!

Another siderake:

Code: Select all

x = 15, y = 9, rule = 6/246/3
9.AB$8.AB.AB$7.AB.2A$6.AB.AB.2A$AB3.AB.2A2.2BA$AB2.AB.AB2.B.A$2.AB2.

Do the B6 and S6 actually do anything? All of these patterns seem to work almost identically in /24/3.

Your sideway rake doesn't work

Brian 6 seems to be a little more dense than Brian's Brain, but the two rules are almost identical...

Just for curiosity's sake, I calculated the density of the smallest exploding seed after 1000 generations in both rules:
Brian's brain: 0.034542
Brian 6: 0.059650
