Smaller Garden of Eden pattern

2006-02-11-orphan-12x12.rle
smaller (12x12) Garden of Eden pattern with 80 ON cells, based on
Achim Flammenkamp's 81-cell 13x12 orphan from 14 June 2004.
Single cell in rightmost column removed, and two other cells moved.
Nicolay Beluchenko, 11 February 2006
Nicolay Beluchenko has modified a previous 'orphan' (Game of Life pattern which has no possible predecessors, and thus can only appear at generation 0) to slightly reduce both the bounding box and the number of ON cells. Changed cells are shown at right: cells only in the original version are in blue, cells only in the new version are in red.

UPDATE: A week after producing the pattern on which Nicolay Beluchenko based his optimized version, Achim Flammenkamp built a smaller Garden of Eden pattern consisting of 72 ON cells inside a 12x11 bounding box. This 23 June 2004 discovery is the smallest Garden of Eden currently known.
