Eric Weisstein's World of Mathematics, Pascal's Triangle

Some rows of Pascal's Triangle:

Row 9 = {1, 9, 36, 84, 126, 126, 84, 36, 9, 1}

Row 10 = {1, 10, 45, 120, 210, 252, 210, 120, 45, 10, 1}

Row 1l = {1, 11, 55, 165, 330, 462, 462, 330, 165, 55, 11, 1}

Looking at this we see the palindromes of 9, 252, 11, and 55 in their order of appearance, without repetition.
