This record for smallest infinitely-growing pattern stood for more than quarter of a century until [[Paul Callahan]] found, in November {{year|1997}}, two 10-cell patterns with infinite growth (it was later determined that twenty-four 10-cell patterns exhibit infinite growth, with 17 unique pattern types). [[Nick Gotts]] and Paul Callahan have since shown that there is no infinite growth pattern with fewer than 10 cells, so the question of the smallest infinite growth pattern in terms of number of cells has been answered completely.</div></td><td class="diff-marker"></td><td style="background-color: #f8f9fa; color: #202122; font-size: 88%; border-style: solid; border-width: 1px 1px 1px 4px; border-radius: 0.33em; border-color: #eaecf0; vertical-align: top; white-space: pre-wrap;"><div>In [[Conway's Game of Life]], the first known pattern to exhibit infinite growth was the [[Gosper glider gun]].
