A new series representation of the Madelung constant is given. We representMadelung constant as a sum of an exact term plus an exponentially fastconverging series. The remarkable result is that even if the series part isdiscarded, one obtains Madelung constant correct up to ten good decimalfigures. This, to the best of our knowledge, may be the fastest convergingseries representation of the Madelung constant. A few other importantidentities are also obtained
