The G4 receiver is an alternate Herschel receiver discovered by Sergey Petrov on 28 December 2011.[1] It accepts a tandem glider labelled G4, meaning that the two glider lanes are separated by four half-diagonals. The first glider triggers a glider to 2 blocks converter, also found by him previously, while the second collides with the half-blockade to release an R-pentomino and an extra 90-degree glider.

In the pattern in the infobox, the R-pentomino is converted to a Herschel by RF28B and BFx59H, whose final output is marked by a ghost Herschel.
