101 is a period-5 oscillator that was found by Achim Flammenkamp on August 19, 1994.[1] The name was suggested by Bill Gosper, noting that one of its phases displays the period in binary.
A 64-glider synthesis of this oscillator was found by Entity Valkyrie on January 10, 2020,[2] which was reduced to 51 gliders by Jeremy Tan soon after.[3] On December 1, 2024, KtT lowered the cost to 32 gliders.[4][5]
While its sparks are de facto inaccessible, there are contrived configurations of cells that make the domino not completely inaccessible, but they rely on an eater 1 catalysis.
