Musing About Palindromes

For those who haven\’t heard before, palindromes are words, phrases, and numbers that \”read the same\” forwards and backwards — words like \”mom,\” \”kayak,\” and \”racecar,\” phrases like \”madam, I\’m Adam\” and \”taco cat,\” and numbers like 24642.

You might have guessed that, because this is a math group, we\’re going to focus on the numbers, and you\’d be right. As you can see, it\’s very easy to see if a number is a palindrome — just read the digits backwards and forwards, and see if you get the same number. It\’s also very easy to generate a palindrome: simply write some digits, like 8364, then reverse them, like 4638, and put those strings of digits together, like 83644638. If you wish you can omit the middle repeated digit, giving a number with an odd number of digits, like 8364638.
