A palindromic number is a 'symmetrical' number like 16461, that remains the same when its digits are reversed. The term palindromic is derived from palindrome, which refers to a word like rotor that remains unchanged under reversal of its letters ... Buckminster Fuller referred to palindromic number as Scheherazade numbers in his book Synergetics, because Scheherazade was the name of the story-telling wife in the 1001 Arabian Nights.
"Shahrazad - possibly the most unusual card ever created, but still fitting with the theme of the set (emulating the "frame story" format of the Arabian Nights tales), Sharazad caused players to start a second game of Magic "inside" the first, which had to be played to completion before returning to the main game. The card was banned for a long time due to fears of it leading to stalemates, but is presently unrestricted in the Vintage and Legacy formats. Due to her weird flavor, a version of Shahrazad called Enter the Dungeon was created for Unhinged."
