A short web document by Ralph Griswold on symmetry operations applied to t-sequences, which are numeric sequences used to generate patterns. It defines horizontal reflection (reversal), vertical reflection (value reversal), and palindrome formation by concatenating a sequence with its reversal. It also introduces "palinforms", concatenations with other reflections, and illustrates each with grid bitmaps and a summary of the notation.
