RR56H is an elementary converter found by Dave Buckingham on September 18, 1996. It accepts an R-pentomino as input and produces an output Herschel 56 ticks later with an extra glider to the southwest. In the pattern shown in the infobox, a ghost Herschel marks the output location.
It is one of the three known blockic (and consequently Spartan) conduits, other two being B60 and R64. The first natural glider from the output is required to clean up a leftover blinker, making the repeat time as high as 113 ticks. Moving the southernmost block three cells down removes both the blinker and the extra glider.
For an application of the extra glider, see the BBx187H converter mentioned in HLx111R.
