p67 B-heptomino hassler is a period-67 oscillator discovered by Nora Brown on April 21, 2023.[1] It uses four block on tables, four drifter-type eater 3 variants, four fishhooks and four blocks to hassle four B-heptominoes. It is the first known period-67 oscillator that is not based on adjustable signal loops.

Chris857 found a 220-glider synthesis on June 29, 2023,[2][3] which he later reduced to 196 gliders on July 8, 2023,[4][5] 184 gliders on August 26, 2023,[6][7] 181 gliders on August 29, 2023,[8][9][10] 169 gliders on January 12, 2024,[11][12] 157 gliders on January 13, 2024,[11][13] and 153 gliders on October 22, 2024.[14][15]
