The Finch Formerly Known As Gold

22 June 2006


Take a number. (Please.) Reverse its digits and add the two together. Take the sum, reverse its digits, and add the two together. Lather, rinse, repeat. Eventually you will reach a numeric palindrome, where the digits read the same forwards and backwards. (For instance, 57 becomes palindromic after two iterations: 57 + 75 = 132, 132 + 231 = 363.)

Or, on rare occasions, you won't. Numbers that don't do this are called Lychrel numbers, and the lowest one known is 196.

Not at all low in any sense is the 196th edition of Carnival of the Vanities, hosted by Rethink(IP), and to their credit, they didn't attempt to rethink the formula at all.
