Big A (or simply A) is a tagalong for two xWSSes which was found by Hartmut Holzwart no later than May 1998. Jason Summers found a 19-glider synthesis for the LWSS variant of the resulting spaceship on September 26, 2007. In August 2009 this synthesis was used to build guns with periods 690 and 144 by Nathaniel Johnston and Matthias Merzenich respectively.
