SUMMARY OF PERFECT SXT ARRAYS, 1-LESS-THAN-OR-EQUAL-TO-S-LESS-THAN-OR-EQUAL-TO-T-LESS-THAN-OR-EQUAL-TO-100

Perfect binary arrays have been the object of investigation by several authors in recent years. This Letter collects known results, including those obtained by combinatorialists in pursuit of a different objective, and applies them to give an account of the status of such arrays of size s x t with 1 less-than-or-equal-to s less-than-or-equal-to t less-than-or-equal-to 100.
