Talk:Total aperiodic

The pattern labelled "Total periodic" is not correct: The block is deleted in gen 220 and has no further effect, so this is a total aperiodic pattern.

Here is Gosper's total periodic pattern, from his email to LifeCA dated 24 Jun 2004.

x = 99, y = 99, rule = S23/B3 40b3o$39bobbo$42bo4b3o$42bo4bobbo4bo$39bobo4bo3bo3b3o$46b4o4boboo$47bo 7b3o$55b3o$41bo13boo$40b3o$39boobo$39b3o$40boo7$39bo$38b3o$37boobo11b 3o$37b3o11bobbo$37b3o14bo$38boo14bo$51bobo3$38bo$39bo$34bo4bo9bo$35b5o 10bo6boo$46bo3bo4booboo$47b4o4b4o$56boo3$55bo$55boo$56boo$23boo30boo$ 3bobbo13b3oboo$7bo12b5o$3bo3bo13b3o12boo$4b4o26booboo$34b4o13b5o$35bo o13bo4bo$24b3o28bo$26bo27bo$24bobo$24boo3$17boo5bobbo$16b4o8bo$5b3o8boo boo3bo3bo$oobb5o9boo5b4o$oobb3oboo$7boo!

It appears that the bottom left part of the pattern got shifted at some point, putting the block in the wrong place.
