HLx111R is an elementary converter found by Matthias Merzenich with ptbsearch in September 2012.[1] Consisting of a cis-snake on bookend (or easier constructed cis-mirrored bookend), a snake (or easier constructed eater 1), an eater 1 and a block, the converter transforms a Herschel to an R-pentomino in 111 ticks.
Its repeat time is 94 ticks, because the first block dropped by Herschel is to be removed by later chaos, instead of an usual eater as in F117.
Next month, Sergey Petrov noticed that if the input Herschel comes from generation 20 of a B-heptomino, then the block it leaves can be deleted with the extra glider from RR56H, resulting in a converter labelled BBx187H with good input clearance.[2] In this case the repeat time depends on different preceding conduits; for example, it is 271 ticks with RF28B, 274 ticks with BRx46B or HF95P + PT9B, 277 ticks with HL75P + PT9B, 278 ticks with HFx58B or 285 ticks with HF94B.
