The unique father problem is the following question, posed by John Conway in 1972 in Lifeline Volume 6 with an associated $50 cash prize,[1] along with the grandfather problem:
- Is there a stable configuration whose only father is itself (with some fading junk some distance away not being counted)?
The problem has been answered positively by Ilkka Törmä, with a 26x32 still-life.Cite error: Invalid parameter "see" in <ref> tag. The supported parameters are: dir, follow, group, name.
