BiLife is a non-totalistic Life-like rule with a common p14 oscillator. All *WSS variants are unstable. The T-tetromino is a common p14 oscillator that frequently appears and gets destroyed a few generations later.
BiHighLife has rulestring B34y6/S23-k5.
BiDryLife has rulestring B34y7/S23-k5.
The T-tetromino mentioned earlier is a p14 oscillator. It also somehow shows off a 21-bit still life
