The rectifier is a 180° stable glider reflector made up of two eater 1s, a block, a beehive, and a modification of eater 3. It is notable for its recovery time of 106 generations and small number of catalysts. It can replace the boojum reflector in a large number of instances, although in some cases it cannot fit into the space provided. Its advantages over the boojum reflector include

• It has a much faster recovery time, allowing certain guns to be compacted;
• Its passive bounding box is slightly smaller, so it can further compact many glider guns;
• Its output path is free of catalysts, enabling it to be used as a merge device.

The transparent beehive reaction was discovered by Paul Callahan in 1996.
