White whale period?

This article claims that White Whale has period, 160,000,346. The glider database claims 160,000,046. I ran this in golly and neither appears to be correct. Gzaytman (talk) 18:48, 25 November 2022 (UTC)

• I think the "hollow" pattern does evolve to a period-160000346 oscillator after 12822176 ticks. The population equals 92 at T = 114375463, 274375809, ... Below are generations T = 0 (top left), 114375463 (top right), 12822175 (bottom left), 160000346 + 12822175 (bottom right). The two patterns in the bottom row converge after one tick.
