4 and 2 now. Interestingly, the rarest still lifes of all other cell counts from 6 to 12 - except 8, as said above - are the respective snakes, by (approximate) factors of 4, >150, 3, 6, 1.3 (after the hook-y amphisbaena), and 1.2 (after the cis-carrier-tie), respectively. This does kind of suggest that the snake should be the rarest SL for every applicable cell count, but the 8 cell example means it's not always true. (I wonder if we'll ever find out what the rarest 14 cell SL is... I'd bet that it won't be the 14-snake, and I would further bet that the 14-snake won't be the last 14 cell SL to appear either.) Apparently the cis-carrier-tie was the rarest 12 cell still life for a while, so it's definitely too early to say for the 13 cells (perhaps it's even too early to say for the 12 cells). For what it's worth, the 13-snake is the third rarest 13 cell SL on record right now (4 occurrences for the 13-snake, 2 for this, and 3 for xs13_0gjl8z1ac).

As of when this comment was written, there are 4 13-snakes and only 1 of this hook w/tail siamese hook w/ tail. A rare object indeed, though we can't really make any statistically sound conclusions yet.

Considering how uncommon a hook-like structure is in Life--hook-with-tail is less common than the 8-snake--might this be rarer than the 13-snake?
