Jormungant's G-to-H is either of two closely related stable 2 glider-to-Herschel converters discovered by Louis-François Handfield (pseudonym: Jormungant) in 2018.[1] It consists of a block, a BTS, and an eater 2 (for the bottom variant) which convert two synchronized gliders into a Herschel with repeat time 47. In the infobox pattern, a ghost Herschel marks the output location.
Unlike most glider-to-Herschel converters, this converter's initial glider-block collision converts the block into a honey farm predecessor, instead of a pi-heptomino. The second glider, along with the BTS catalyst, convert the pre–honey farm into a B-heptomino, which forms a block at the original location and produces a Herschel output. There are two possible positions for this second glider; one of these requires the presence of an additional eater 2, as well as replacing the BTS with an equivalent larger catalyst with better clearance.
It is the basis of various low-period guns, for example p13-assisted period-52 glider gun. Without this, it would take 3 gliders to create a Herschel by using the glider synthesis of a B-heptomino, plus one extra glider to delete the B-heptomino's block. In cases such as the original period-52 glider gun, this would not be sufficient to create an over-unity reaction due to the difficulty of extracting 4 gliders from an output Herschel at such a low period. The discovery of this fast 2G-to-H was thus a key innovation allowing these low-period guns to be constructed.
