Disappointment

So I was playing around with a version of Conway's Game of Life on my iPhone the other day, and got really excited that I had discovered a stable repeating pattern:

Looked to me like a size 48, 72 generation oscillator. It's made up of two small size 16, 8 generation oscillators and two 4-cell blocks stabilizing a small back-and-forth shuttle. Here's one of the smaller oscillators (the other is top-bottom mirror symmetric):

Of course, millions of people have been playing around with Conway's Game of Life for 40 years, so it might have been found before. But, it's large enough that I thought there was a chance it might be novel. And initial searches seemed to bear out my hopes: There are no described 48-cell, period-72 oscillators.

But, alas, it was not to be: The penultimate state, although much less attractive, has a size of only 47 cells:

And someone had, in fact, already discovered it. However, I discovered it independently, goddamnit, and if Leibniz gets co-credit for calculus, then this will damn well be Bryan's 48-Cell Oscillator. :)

But I guess Stephen Wolfram is still safe as the reigning champion of cellular automata.

For now...
