It's hard to believe that this rule is just 2 transitions away from life. The block, the most common still life in almost all 2TFL rules, is almost 100 times less common than the most common period 2 oscillator, the duoplet. Even the more common 4 cell still life, the z-tetromino, is 15 times more common than the block. On the other hand, I'm pretty confident that it's easily possible to make complex circuitry in this rule.

Some objects in B36n/S234w

The oscillators are period 6, 8, 9, 10, 20, and 66 and they don't work in b3s23.

The orthogonal spaceships are, from left to right, c/2, 2c/5, c/3, 2c/7, c/4, c/5, c/6, and c/7.

The diagonal ones are 2c/3, 4c/7, c/4, c/6, and c/116
