article published yes Yuval Wigderson author 2d0023a0-1567-11f0-833d-d5c1e476d4b5 A recent breakthrough of Conlon and Ferber yielded an exponential improvement on the lower bounds for multicolor diagonal Ramsey numbers. In this note, we modify their construction and obtain improved bounds for more than three colors.
