PD-pair reflector is a pair of pentadecathlons arranged so that their V sparks turn a glider by 90 (or 180) degrees. The minimum repeat time is 45 ticks. This reaction was found by Mark Niemiec on 6 January 1996, which is relatively recent considering how old pentadecathlon technology is. It turns a glider into a block, and then that block into a glider.
