Isn’t it pi/century shuttle?

[confocaloid]

When someone posts a pi shuttle that also turns out to be a century shuttle (with century appearing in a different phase), there is no requirement for them to describe it as such; it is possible that they simply didn't notice.

That said, it looks like removing the shuttled active object causes the rest to fail, which means that shuttleness/hasslerness of that p62 oscillator is dubious, at least with that way to separate it into the "hassled" part and the "hassling" part.

My initial thought for the name of the p21 oscillator was "blackjack", as not only is a p21, it's 11+10, where a blackjack in the game is formed of an 11-point card and a 10-point card.

Then the 13+8 form showed up, somewhat undermining that name. I'd still support it, though.
